Answer:
x = -5, 1
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from 
.
-1 and 5 multiply to -5 and add to 4.
The zeros are the factors set equal to 0 and solved.
(x+5) = 0
x=-5
(x-1) = 0
x=1
Answer:
13.5
Step-by-step explanation:
the answer is 13.5, because you do the proportionate equations of 6/4 = x/9, and then you cross multiply to get 4x=54, and then you isolate x, so the answer is 13.5
Answer:
100 m^2.
Step-by-step explanation:
The area of a trapezoid = (h/2) (a + b) where h = the perpendicular distance between the 2 parallel sides and a and b are the lengths of the 2 parallel sides.
Here we have Area = (1/2 * 10) ( 8 + 12)
= 5 * 20
= 100 m^2.
