NEED ANSWERS ASAP The two triangles are similar. What is the value of x?

1 answer:

4 0

If the two triangles are similar, then by definition we have that the quotient between two sides of a triangle is equal to the quotient between two sides of the second triangle.
We have then:
((3x) / (4x + 2)) = ((20) / (28))
Clearing:
3x = (20/28) * (4x + 2)
28 * 3x = (20) * (4x + 2)
84x = 80x + 40
84x-80x = 40
4x = 40
x = (40) / (4)
x = 10
answer
The value of x is 10

Answer:

(a). 32 copies

(b). $3060

Step-by-step explanation:

Solution for (a):

P = 60c + 1800

If P is $3720 then;

3720 = 60c + 1800

60c = 3720 - 1800 = 1920

c = $\frac{1920}{60}$ = 32 copies

Solution for (b):

P = 60c + 1800

If c is 21 then;

P = $60(21) + $1800

P = $1260 + $1800

P = $3060

Answer:

105 yards

Step-by-step explanation:

The other side is Width = 374/17 = 22.

So, the new width is 44 ( and the length is 17/2).

Perimeter = 2(17/2) + 2(44) = 17+88=105 yds.

So, 105 yards.
