X =7, -4.
Make the equation x2 -3x -28
Factor to get x-7 and x+4. Then find the opposite to find what x is
Answer:
A.
Step-by-step Explanation:
P(A or B) = P(A)+P(B)-P(A and B)
Now
Putting the givens
0.68 = 0.2 + P(B) - 0.12
P(B) = 0.68 - 0.2 +0.12
P(B) = 0.6
Answer:
26 square meters (the first option)
Step-by-step explanation:
The area of a trapezoid is (b1+b2)/2*h.
b1=one of the bases (one of the bases that are parallel to each other)
b2= the other base (that is parallel to base 1)
h=height
In this picture, b1=5, b2=8, h=4
So, the area is
(5+8)/2*4
=13/2*4
=6.5*4
= 26 square meters
