Answer:
A
Step-by-step explanation:
The area of the large triangle is 36*24/2
minus the small triangle which is 21*14/2
so 432-147 = 285
12*12=144
x*x=x squared
answer=12x
Answer:
Area=15
Step-by-step explanation:
Area=bh1/2
6*5=30
30*1/2
15
<span>2 x - y - 7 = 0
y =2x - 7 slope = 2
</span><span>perpendicular slope = -1/2
</span><span>line passing through point (4, -1)
y = mx + b
-1=-1/2(4) + b
-1 = - 2 + b
b = 1
equation
y =-1/2(x) + 1</span>
First find the increase in books
144-76 = 68
Next find the percentage for 68
68/144 = 0.47222
0.47*100 = 47%
