I need this answer badly

Part A: C

Part B: B

Step-by-step explanation:

x represents the missing value- the number of boards. Its multiplied by 6, so we know it must be the number of boards in 1 kit.

Let's solve the equation:

6(x + 18) = 192 multiply

6x + 108 = 192 subtract

6x = 84divide

x = 14

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.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
