Ox2 + x - 72 = 0
O x2 + x + 72 = 0
O x2 + 2x - 72 = 0
o x2 + 2x + 72 = 0
Answer:
x^2 + x - 72 = 0
Step-by-step explanation:
x(x + 1) = 72 should be re-written in the standard form of a quadratic:
x^2 + x - 72 = 0. Same as the first answer choice.
Answer:
x^2+x-72=0
Step-by-step explanation:
Answer:
(0,0)
Step-by-step explanation:
To find the x intercept we set y = 0 and solve for x
10x = -5y
10x = 0
x =0
To find the y intercept we set x = 0 and solve for y
10x = -5y
0 = -5y
0=y
The x and y intercepts are 0
(0,0)
Answer:
x = 80
Step-by-step explanation:
Answer:
Step-by-step explanation:
we know that
in a parallelogram, opposite sides are congruent
In this problem
AB and DC are opposite sides
therefore
AB=DC
substitute the given values
solve for x
Find the length of side DC
substitute the value of x
