Step-by-step explanation:

Use the distributive property to factor a monomial out of a polynomial. Factors are numbers that multiply together to produce another number. For example, 2 and 10 are factors of 20, as are 4 and 5 and 1 and 20. Factoring is the process of breaking a number down into its multiplicative factors.

Answer: Factoring is the opposite of using the distributive property to multiply. If you had: 7(3x + 8), you would distribute the 7 and multiply it both both terms. Factoring reverses that process.

Answer:

x = -1

y = 1

Step-by-step explanation:

x + 2y = 1     (Multiply this by -2)

2x + 5y = 3

-2x - 4y = -2

2x + 5y = 3

y = 1

x + 2y = 1

x + 2(1) = 1

x + 2 = 1

x = 1 - 2

x = -1

Answer:

x = -1

y = 1

Step By Step Explanation:

x + 2y = 1

2x + 5y = 3

let x become the subject. use one of the equation.

x = 1 - 2y

substitute into another equation

2(1 - 2y) + 5y = 3

expend the bracket

2 - 4y + 5y = 3

collect like terms

- 4y + 5y = 3 - 2

y = 1

substitute into one of the equation to find x

x + 2y = 1

x + 2 (1) = 1

x + 2 = 1

collect like terms

x = 1 - 2

x = - 1

Answer:

22.96 cm

Step-by-step explanation:

Let the point of contact of the tangent with the circle be R.

Let the centre of the circle be O.

We are told that from Point P, the length of the tangent is 24 cm.

Thus, PR = 24 cm

Now, the radius will be perpendicular to the tangent at the point of contact with the circle.

Thus, ORP will form a right angle triangle where ∠R = 90°

Since radius = 7 cm, we can use pythagoras theorem to find OP which is the distance of P from the centre.

Thus;

OP = √(24² - 7²)

OP = √527

OP = 22.96 cm

Answer:

7

8

Step-by-step explanation:

The rate of change per year is the number of books she gets each year.

The problem states "She will buy 7 new puzzle of books each year."

The rate of change per year is 7.

The initial value is the beginning value.

She gets 7 book each year. In 5 years, she gets 5 * 7 = 35 books.

She will have 35 additional books in 5 years. She will have a total of 43 books in 5 years.

43 - 35 = 8

She started with 8 books.

The initial value is 8.

Answer:

y - 2 = (-1/4)(x - 8)

Step-by-step explanation:

The slope of the given line is 4.  The slope of any line perpendicular to the given line is the negative reciprocal of 4, which is -1/4.

Use the point-slope formula:

y - k = m(x - h), where (h, k) is the given point.

Then:  y - 2 = (-1/4)(x - 8)

Answer:

The first person to arrive is not random. The person that mostly arrives first every time is the person who lives closest to the school, or is a teacher's pet.

The odds of the person who lives 20km away from the school being first are way lower than anyone else.

A better method, would be everyone writes their name on a paper, and the teacher picks one at random from a hat.

Answer:

2248+2224.91= 4472.91

Step-by-step explanation:

A = $2,248.00

I = A - P = $248.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 3.1%/100 = 0.031 per year.

Solving our equation:

A = 2000(1 + (0.031 × 4)) = 2248

A = $2,248.00

The total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 3.1% per year for 4 years is $2,248.00.

A = $2,224.91

A = P + I where

P (principal) = $2,000.00

I (interest) = $224.91

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.7/100

r = 0.027 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,000.00(1 + 0.027/1)(1)(4)

A = 2,000.00(1 + 0.027)(4)

A = $2,224.91

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 2.7% per year compounded 1 times per year over 4 years is $2,224.91.

Answer:

18 shirts can be made and 130 cm of clothes will remain unstitched.

Step-by-step explanation:

Given that,

Total length of the cloth = 40 m = 4000 cm

Amount needed to stitch a shirt = 2m 15cm = 215 cm

Now dividing 4000 by 215 to get the number of shirts that can be stitched and no. of shirts remain. After dividing, we get quotient as 18 and remainder as 130.

So, 18 shirts can be made and 130 cm of clothes will remain unstitched.

Answer:

As 252 has more than two factors, this makes it a composite number. As the sum of digits of 252 is 9, it is divisible by 3 as well as 9. Hence, 3 and 9 are factors of 252.

Answer:

[tex] \huge \orange{m\widehat {FGH} =238\degree} [/tex]

Step-by-step explanation:

[tex] \therefore m\angle FGH + m\angle FAH = 180\degree [/tex]

[tex] \therefore (21x-2)\degree + (38x +5)\degree = 180\degree [/tex]

[tex] \therefore (21x-2+38x +5)\degree = 180\degree [/tex]

[tex] \therefore 59x+3= 180[/tex]

[tex] \therefore 59x= 180-3 [/tex]

[tex] \therefore 59x= 177 [/tex]

[tex] \therefore x= \frac{177}{59}[/tex]

[tex] \therefore x=3[/tex]

Now, by inscribed angle theorem:

[tex] m\angle FAH = \frac{1}{2} m\widehat {FGH} [/tex]

[tex] (38x +5)\degree = \frac{1}{2} m\widehat {FGH} [/tex]

[tex] 2(38\times 3+5)\degree = m\widehat {FGH} [/tex]

[tex] 2(119)\degree = m\widehat {FGH} [/tex]

[tex] 238\degree = m\widehat {FGH} [/tex]

[tex] \huge \purple {\boxed {m\widehat {FGH} =238\degree}} [/tex]

Answer: 121°

Step-by-step explanation:

The measure of angle B will be [tex]121^0[/tex] .

Angle is formed by two rays lie in the plane that contains the rays.

We have,

[tex]m \angle A =(6x-19)^0[/tex]

Now,

Linear pair angles are those angles whose sum is [tex]180^0[/tex] .

i.e.

[tex]m \angle A + m \angle B=180^0[/tex]

So,

[tex](6x-19)^0 +(11x-22)^0 =180^0[/tex]

Now,

[tex]17x-41=180[/tex]

[tex]17x=221[/tex]

[tex]x=13[/tex]

So,

[tex]m\angle B=(11x-22)^0[/tex]

Putting value of x;

[tex]m\angle B=(11*13-22)^0[/tex]

[tex]m\angle B=(121)^0[/tex]

So, measure of angle B is [tex]121^0[/tex].

Hence, we can say that the measure of angle B will be [tex]121^0[/tex] .
