a.15
b. 21
c.24
d.48

a

Step-by-step explanation:

In evaluating the expression multiplication is performed before addition.

given

9 + 3 × 2 ← perform the multiplication

= 9 + 6 ← perform the addition

= 15 → a

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.
