Answer:

A

Step-by-step explanation:

(x-4)^2=5

(x-4)(x-4)=5

x(x-4)-4(x-4)=5

distribute

x^2-4x-4x+16=5

combine like terms

x^2-8x+16=5

move terms to the left and combine

x^2-8x+11=0

use the quadratic formula and simplify

x=-(-8)+/-2 to the square roots of 5 over 2

separate and solve

x=4+ square root of 5

x=4- square root of 5

ANSWER: x=4+/- square root of 5

Answer:

x=21

Step-by-step explanation:

17x + 50 should equal to 19x + 8

so,

50 - 8 = 42 it means 42 shoul equal to (19x - 17x) = 2x.

so if 2x = 42 = 2x/2 = 42/2 = x = 21...

Answer:

x=1

Step-by-step explanation:

Answer:

x= 1  and x= -1

Step-by-step explanation:

[tex]5x^{2} +2=7[/tex]

(subtract 2 from both sides)

[tex]5x^{2} =5[/tex]

(divide by 5 from both sides)

[tex]x^{2} =1[/tex]

(take the square root from both sides)

x=±√1

so,

x= 1

and

x= -1

Answer:

Your correct answer is x = 42 .

My Step-by-step explanation:

Just turn the problem around by changing the subtraction to addition: 100 – x = 58 means the same thing as 100 – 58 = x, so x = 42.

Suppose the cost of each t-shirt is x

and the cost of each hat is y

according to question

[tex]\Rightarrow 2x+3y=12\quad \ldots(i)\\\Rightarrow 5x+4y=23\quad \ldots(ii)\\\text{solving (i) and (ii) we get}[/tex]

[tex]x=3\ \text{and}\ y=2[/tex]

So, the cost of a t-shirt is £3

the cost of a hat is £2

Answer:

  25.8°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the trig relations in a right triangle.

  Cos = Adjacent/Hypotenuse

  cos(x) = (9 cm)/(10 cm) = 0.9

Using the inverse cosine function, we can find the angle given its cosine.

  x = arccos(0.9) ≈ 25.8°

Angle x is about 25.8°.

Answer:

8 Inches

Step-by-step explanation:

multiply the length value by 4

Answer:

[tex] \frac{8\pi}{5}[/tex]

Step-by-step explanation:

Since this is a degree we going to use the arc length formula

[tex]2\pi \times( r)( \frac{x}{360)} [/tex]

where x is the central angle measure and r is the radius.

The radius is 6 and the central angle is 48 so let plug that in the formula

[tex]2\pi \times (6)( \frac{48}{360} )[/tex]

Multiply 2 pi by 6

[tex]12\pi \times ( \frac{48}{360} )[/tex]

[tex]12\pi \times \frac{4}{30} [/tex]

[tex] \frac{12\pi}{1} \times \frac{4}{30} = \frac{48\pi}{30} [/tex]

[tex] \frac{8\pi}{5} [/tex]

Answer:

A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is (5 ) units. the point (-7, -1) and point (-7, 5) lies in this circle.

Step-by-step explanation:

equation of circle is

(X-center_X)^2 + (y-center_Y)^2 = r^2

==> (x+3)^2 + (y-2)^2 = r^2

Now it passes 1,5 so

4^2+3^2 = 5^2

==> r = 5

when x = -7

y = -1 or 5

Answer:

yes, the volume would be increased by 4

Step-by-step explanation:

the volume for a box is l x w x h

lets say l = 4, w = 3, and h = 2

this would give us a volume of 24

now calculate the new volume: l x w x 4h

4 x 3 x (4 x 2) = 96 which is 4 times bigger than 24

Answer:

89, 78, 67, 56

Step-by-step explanation:

The next four terms of the arithmetic sequence is

As we can see that from the given sequence that 11 is deducted from each following number

122, 111, 100, 89, 78, 67, 56

122, (122 - 11), (111 - 11)

So the above represent the next four terms

Correct method to factor this expression are:

Factor by grouping.

Factor out the GCF.

A number or other mathematical object is factorised or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort. The four primary methods of factoring are the Grouping technique, the Difference in Two Squares, the Sum or Difference in Cubes, and the Greatest Common Factor (GCF). Numerous issues might be resolved by using the factoring of integers. Similar to this, factoring is an extremely effective method in algebra that is utilised at all levels. It offers a common approach to simplifying complex statements as well as, of course, solving quadratic equations.

The equation becomes:

= 4x² - 26x + 30

= 2 (2x² - 13x + 15)

= 2 (2x² - 10x - 3x + 15)

= 2 {2x (x - 5) - 3 (x - 5)}

= 2 (2x - 3) (x - 5)

Thus, the two methods are the best choices to factor this express are:

Factor by grouping.

Factor out the GCF.
