8/x-7=7/2
16=7(x-7) cross multiply
16=7x-49

-7x/7=-65/7
X=65/7
Alternative form
X=92/7
Which is 1st options in your questions.

Hope this helps!

Answer:

Dilate Circle A by a scale factor of 4.

Step-by-step explanation:

Figure 1 shows Circles A (red) and B (green) before any transformations.

Figure 2 shows Circle A dilated about its centre by a factor of 4.

It is now apparent that every radius in A' has a corresponding radius in B, so the circles are similar.

The diagram shows a metal plate in the shape of a rectangle. The rectangle has length 20 cm and width 12 cm. Two identical circl
Anna007 [38]

Answer:

A ≈ 183 cm²

Step-by-step explanation:

Step 1: Find the area of the 2 circles

A = πr²

r = 6/2 = 3

A = π(3)²

A = 9π

Since there are <em>2</em> circles, 9π(2) = 18π

Step 2: Find area of <em>entire </em>rectangle

A = lw

A = 12(20)

A = 240

Step 3: Subtract the area of the circles from the area of the entire rectangle

240 - 18π

Shaded area = 183.451 cm²

And we have our answer!
