Answer:

x= 4

(not sure about a, sorry friend)

Step-by-step explanation:

Since the shape is congruent with the other sides it's the same.

Answer:

(a) P = 32.5 feet

(b) P = 108-2x feet

Step-by-step explanation:

Note: Perimeter is the total distance around the border of a shape.

(a)

P = 14' + 27'' + 14' +27'' ; First we have to covert the 27'' (27 inches to feet)

[tex]27*\frac{1}{12} = \frac{27}{12} =\frac{9}{4}[/tex] = 2.25feet

P = 14'+2.25'+14'+2.25'

P = 32.5' = 32.5 feet

(b)

P = 15'+29'+(15'-x')+3'+7'+3'+(7'-x')+29' ; where x is the overlapping distance of the 2 rectangles of Foundation B.

P = 108' -2x'

P = 108-2x feet

Note: there is not enough information to determine the vaule of x from the problem.

Answer:

Step-by-step explanation:

Angle DBC and angle BDA form a pair of vertical angles, not a pair of alternate interior angles, which are congruent.

Triangles ABD and CDB are congruent by the SAS postulate instead of the SSS postulate.

Triangles ABD and BCD are congruent by the AAS postulate instead of the SSS postulate.

Angle DBC and angle BDA form a pair of corresponding angles, not a pair of alternate interior angles, which are congruent.

Answer:

[tex]7x^3(7x^2-9 )[/tex]

Step-by-step explanation:

To factor, you have to find the GCF of 49 and 63 and the GCF of [tex]x^{5}[/tex] and [tex]x^3[/tex]

Factor 49: 1,7, and 49

Factor 63: 1, 3, 7, 9, 21, 63

Factor [tex]x^{5}[/tex]: [tex]x*x*x*x*x[/tex]

Factor [tex]x^3[/tex]: [tex]x*x*x[/tex]

So the GCF of 49 and 63 is 7

The GCF of [tex]x^{5}[/tex] and [tex]x^{3}[/tex] is [tex]x^3[/tex]

We multiply 7 by [tex]x^{3}[/tex] to get [tex]7x^3[/tex]

So now we start to factor out the GCF of [tex]49x^5-63x^3[/tex]

[tex]7x^3(\frac{49x^5}{7x^3}+ \frac{63x^3}{7x^3} )[/tex]

[tex]\frac{49}{7} =7\\x^5-x^3=x^2[/tex]

[tex]\frac{63}{7} =9\\x^3-x^3=x^0[/tex] because [tex]x^{0}[/tex] can't be written as an exponent we don't write [tex]9x^0[/tex]

When we factor we get [tex]7x^3(7x^2-9 )[/tex]

Answer:

The first choice:

x: -5, -4, -3, -2, -1

y: -5, -3,  -1,   1,  3

Step-by-step explanation:

If we apply the equation here...

y = 2x + 5

(Let's use -1 for example)

y = 2(-1) + 5 --> y = -2+5, which gives us 3

On the table, it says that the y is 3, so it proves that it is correct

If you apply the equation for all of the x's, it'll give you the y's for the first choice. This doesn't apply to the rest of the tables, so the first table is the correct choice

The values are satisfied by

x      y

-5    -5

-4    -3

-3    -1

-2     1

-1      3

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given:

Y= 2X +5

let us put the value for X

X= 0

Y = 5

and, X=1

Y = 2 + 5 = 7

and, X= 2

Y= 4 + 5 = 9

and, X=3

Y = 6 + 5 = 11

and, X= 5

Y = 10 + 5= 15

and, X= -1

Y= -2 + 5 = 3

Hence, these values are satisfied by

x      y

-5    -5

-4    -3

-3    -1

-2     1

-1      3

Answer:

66 robots

Step-by-step explanation:

So they are telling you to DIVIDE the amount of dollars earned to the price of the toy robots.

> 792 / 12 = ?

> 79 - 72 = 7 ( sis 12s goes into 79 )

> 72 - 72 = 0 ( six 12s goes into 72 evenly )

> 792 / 12 = 66

So the store has selled 66 toy robots & earned a profit of $792.

1. Percent change - 14.5455% ≈ 15% | decrease

2. Percent change - 30.2326% ≈ 30% | increase

3.  New price - $83.74

4. New price - $436.50

Step-by-step explanation:

To find an increase or decrease in price, if you have the percent provided, convert the percent into a decimal, then multiply the percent by the price, if it's an increase, add the price by the sum, if it's a decrease, subtract the price by the sum.

Answer:

y = −3/1 x−2

​

Step-by-step explanation:

1,3,5,7 = 126°

2,4,6,8 = 54°

Here your go m'dear

Given, ∠3 = 126°.

∠3 =∠1 = 126° (vertically opp. angles)

∠3 =∠5 = 126° (alternate interior angles)

∠3 =∠7 = 126° (corresponding angles)

Now, ∠2 = 180° - 126° = 54° (linear pair/supplementary angles)

∠2 = ∠4 = 54° (vertically opp. angles)

∠2 = ∠8 = 54° (alternate interior angles)

∠8 = ∠6 = 54° (vertically opp. angles)

Answer:

ALL of the following expressions are NOT equivalent to 64^5t^2+3t

Step-By-Step Explanation:

Khan Academy

To determine whether each expression is equivalent to [tex]64^5t^2 + 3t[/tex], we will simplify each expression by evaluating the calculations.

Expression 1:   [tex]64^5t^2 + 3t[/tex]

Expression 2:  [tex](4^3)^5t^2 + 3t = 4^(3*5)t^2 + 3t = 4^15t^2 + 3t[/tex]  

Expression  3:  [tex](8^2)^5t^2 + 3t = 8^(2*5)t^2 + 3t = 8^10t^2 + 3t[/tex]  

Expression 4:   [tex](2^6)^5t^2 + 3t = 2^(6*5)t^2 + 3t = 2^30t^2 + 3t[/tex]  

Expression 5:   [tex](8^8)^3t^2 + 3t = 8^(8*3)t^2 + 3t = 8^24t^2 + 3t[/tex]  

Expression 6:   [tex]64^5t^2 + t + 2t = 64^5t^2 + 3t[/tex]

After evaluating each expression, we can see that all the expressions are equivalent to [tex]64^5t^2 + 3t[/tex]. The calculations show that regardless of the specific values used, the expressions simplify to the same result. Therefore, it can be concluded that all six expressions are equivalent to [tex]64^5t^2 + 3t.[/tex]

y = -3x + 11

Step-by-step explanation:

To find the equation of the line we would plug in the given info into the point slope equation:

[tex]y-y_{1} =m(x - x_{1} )[/tex]

In this case (x1, y1) is (4, -1) and m is -3:

y - (-1) = -3(x - 4)

We can simplify as follows:

y + 1 = -3x + 12

y = -3x + 11

Answer:

g+r=15  and 2.00g+4.50r=37.50 are the two equations you need to use

Step-by-step explanation: IM NOT COMPLETLEY SURE THO

Answer: C

The total number of pounds of trail mix is 15. The pounds of granola added to the pounds raisins has to equal 15. So, one of the equations is g + r=15.

In total the cost of the granola and the cost of the raisins must be equal to $37.50. Since the granola costs $2 per pound and the raisins cost $4.50 per pound, 2g + 4.5r= 37.5.
