Answer:
B and D
Step-by-step explanation:
Write as a quadratic
-2x² - 3x + 5 = 0
Factor
-2x² - 5x + 2x + 5 = 0
-x(2x + 5) + 1(2x + 5) = 0
(1 - x)(2x + 5) = 0
To make the equation 0, x is either 1 or -5/2.
Answer: B) -5
Step-by-step explanation: all you do is subtract 12 from each side and you will get -5
I got 63,000 because it simplifies to 45*35*4
Answer:
pm+2=8
Step-by-step explanation:
Given,
m=3
p=3
We know,
pm+2=3(3)+2
=3×3+2
=6+2
=8
Area= l*b
0.8=3.2*x
0.8/3.2=x
x=0.25 units
