Which of the following is equivalent to -21(6 - 71)? a (0 – 21(6-71)
b (0 + 206 - 71)
c (-2 + 1)(6 – 71)
d (6-21) – (71-21)

a

Step-by-step explanation:

-21(-65)

= - 86

A

(0-21(6-71)

(-21-65)=-86

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
