*see attachment for the diagram of the wall
Answer:
6 cans
Step-by-step explanation:
First, let's calculate the area of the wall to be painted = area of a rectangle
Area of the rectangle = length*width
From the diagram,
Length = 13 ft
Width = 10 ft
Area = 13*10 = 130 ft²
Given that 1 can of paint covers 25 ft²,
Number of can of paints that will cover 130 ft² = 130/25 = 5.2
This means we will need more than 5 cans. So Joan will need to get roughly 6 cams of blackboard paint.
A:{(7,9),(13,6),(3,9),(11,-4),(1,7)}. inverse={(9,7),(6,13)(9,3),(-4,11),(7,1)}
B:{(11,8),(5,6),(3,7),(21,2),(2,5)} inverse={(8,11),(6,5)(7,3),(2,21),(5,2)}
work is pictured and shown
So when we factor out: , we get:
Therefore, we see that in this case, a = -7 and b =10.
So then a + b will equal -7 + 10, which equals B) 3.
yea i can help
log4(1/4x^2) so its A
