Answer:
4
Step-by-step explanation:
as BC║DE
so, AD:BD=AE:CE
or, CE=(BDₓAE)/AD
or, x=(5×16)/20=4
Answer:
m=17
Step-by-step explanation:
Complementary means they add to equal 90 degrees.
1) 90-A=36
2)36=2x+2
3) Subtract 2 from both sides, 34=2x
4) Divide by 2 17=x
Factor x^3+8
x^3+8
=(x+2)(x^2−2x+4)
Answer:
(x+2)(x^2−2x+4)

Answer:
B.
Step-by-step explanation:
The Commutative Property of Addition states that numbers can be switched around. This equation doesn't have a definitive order and the equation allows you to switch around the numbers.
Answer:
∠ A = 56°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2x + 3x + 40 = 180
5x + 40 = 180 ( subtract 40 from both sides )
5x = 140 ( divide both sides by 5 )
x = 28
then
∠ A = 2x = 2 × 28 = 56°
