What value of z will make △DEF ≅ △JKI

Leto [7]

Answer:

z = 11

Explanation:

5y + 13 = 6y

Subtract 5y by both sides.

13 = y

Next,

z + 22 = 3z

Subtract z by both sides.

22 = 2z

Then, divide both sides by 2.

11 = z

Finally plug those answers into the equations.

5(13) + 13 = 78

6(13) = 78

(11) + 22 = 33

3(11) = 33

So △DEF ≅ △JKI because the value of z = 11.

Which of the equations are true identities? a. (3x-2y)(2y-3x)=9x^2-4y^2 b. (2k+5r)(2k-5r)=4k^2-25r^2

krok68 [10]

Answer:

b. $(2k+5r)(2k-5r)$

Step-by-step explanation:

We have to find the equation which are true identity.

a. $(3-2y)(2y-3x)$

$(3x-2y)(2y-3x)=3x(2y-3x)-2y(2y-3x)$

$=6xy-9x^2-4y^2+6xy$

$(3-2y)(2y-3x)\neq 9x^2-4y^2$

b. $(2k+5r)(2k-5r)$

$(2k)^2-(5r)^2$

Using identity

$(a+b)(a-b)=a^2-b^2$

$4k^2-25r^2$

It is true.

Hence, option b is true.

What is the perimeter of one triangle?

forsale [732]

Answer:

Perimeter =84 inches (12 + 35 + 37

Step-by-step explanation:

12 squared + 35 squared = x squared (the other unknown side)

144 +1225 = x squared

1369 = x squared

square root of 1369 = x

x= 37 (37x37= 1369)

Perimeter = 12 +35 + 37 = 84
