a. 88%
b. 80%
Step-by-step explanation:
198/225=.88
180/225=.80
Area=legnth times width=31
the frame must go around the frame with equal legnth, x
so
the total area (meaning the frame +picture) is 5+x by 6+x
31=(5+x)(6+x)
expand
31=30+11x+x^2
minus 31 both sides
0=-1+11x+x^2
x^2+11x-1=0
answer is third one
The correct answer is: x=9
4(1-x)+2=-3(x+1 )
-4x +3x = -3 -6
-x=-9
x=9
Answer:
m (Slope) = 3
Step-by-step explanation:
Slope formula:
m = (y2 - y1) / (x2 - x1)
= (24 - 3) / (9 -2)
= 21 / 7
=3
