2.49/6 = 0.415
3.32/8 = 0.415
unit rates are equal :)
Answer:
Comprimento: 28.9 m; Largura: 11.1 m
Step-by-step explanation:
P = 2(C + L) = 80
A = CL = 320
2(C + L) = 80
CL = 320
C + L = 40
CL = 320
C = 40 - L
CL = 320
(40 - L)L = 320
40L - L^2 = 320
L^2 - 40L + 320 = 0
aL^2 + bL + c = 0
or
L = 28.9
C = 40 - L = 40 - 28.9 = 11.1
Answer: Comprimento: 28.9 m; Largura: 11.1 m
Answer:
y=1/2+1
Step-by-step explanation:
1) Y2-Y1 over X2-X1
<u>9-5=4</u>
12-4=8
4/8 simplify the answer= 1/2
m=1/2
2) subtitute the simplification to one of the points.
y=mx+b
5=1(4)+b
5=4=b
1=b
y=1/2+1
