Answer:

x = -5

Step-by-step explanation:

Original equation:

2(2x - 7) = -34

Use distributive property

2 · 2x = 4x

2 · (-7) = -14

Plug these values back into the equation

4x - 14 = -34

Add 14 to both sides

4x = -20

Divide both sides by 4

x = -5

Hope this helps :)

The area of the small shape is 35 square feet. The big shape is larger by a scale factor of 4/3. Find the area of the large shap

sdas [7]

Answer:

Option a) 62.2 square feet

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produces similar figures

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x ----> the area of the large shape

y ----> the area of the small shape

$z^{2}=\frac{x}{y}$

we have

$z=\frac{4}{3}$

$y=35\ ft^2$

substitute

$(\frac{4}{3})^{2}=\frac{x}{35}$

$\frac{16}{9}=\frac{x}{35}$

solve for x

$x=\frac{16}{9}(35)=62.2\ ft^2$

the rectangle shown has a perimeter of 40cm and the given area of 64 cm squared it's length is 8 more than twice its width write

notka56 [123]

Answer:

16 = l

4 = w

Step-by-step explanation:

{64 = wl

{40 = 2w + 2l

{l = 8 + 2w

64 = w[8 + 2w] ↷

-64 + 8w + 2w² ↷

[2w² - 8w] + [16w - 64]

2w[w - 4] 16[w - 4]

[w - 4][2w + 16] = 0

↑

This is the expression we want because when we talk about dimensions, we want NON-NEGATIVE numbers. The other expression results in -8 = w, and we do not want that; this expression gives us a solution of 4 = w, and THIS is exactly what we want. Anyway, you plug "4" back into the system of equations and you will get a length of 16 centimetres.

I am joyous to assist you anytime.
