Answer:
x = 6
Step-by-step explanation:
to evaluate this 1/2 (4x + 16) = 20 we need to open the bracket and then cross multiply and finally evaluate for the value of x
1/2 (4x + 16) = 20
4x + 16 = 2 x 20 ............................... using cross multiplication
4x + 16 = 40
combine the like terms together
4x = 40 -16
4x = 24
divide both sides by the coefficient of x
4x/4 = 24/4
x = 6
therefore the value of x in the expression 1/2 (4x + 16) = 20 is evaluated to be equals to 6
Answer:
The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two. The figure shows two right triangles that are each missing one side's measure.

Answer:
Step-by-step explanation:
1. 1 Simplify 2+6-4d to -4d+8.
7 ( -4d + 8)
therefor, the answer is, 7( -4d + 8)
