Answer:
See below.
Step-by-step explanation:
Variables:
L = length
W = width
P = perimeter
Equations:
L = W + 13
P = 2(L + W)
P = 2(W + 13 + W)
2(W + 13 + W) = 226
2(2W + 13) = 226
2W + 13 = 113
2W = 100
W = 50
L = W + 13 = 50 + 13 = 63
The length is 63 cm, and the width is 50 cm.
Answer:
19 yards squared
Step-by-step explanation:
3x5=15
2x2=4
15+4=19
Answer:
84
Step-by-step explanation:
A rhombus has parallel sides so it's simply
24+24+18+18=84
So megan is four years younger than her aunt
m+4=a
or
m=a-4
the sum of their ages is at least 40
m+a<u>></u>40
subsitute a-4 for m
a-4+a<u /><u>></u>40
combine like terms
2a-4<u>></u>40
the answer is the third from the top
9514 1404 393
Answer:
Step-by-step explanation:
The slope of the given line can be found from the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4 -1)/(3 -2) = 3/1 = 3
The slope of the perpendicular line is the opposite reciprocal of this:
perpendicular slope = -1/m = -1/3
__
Choices (c) and (d) have x-coefficients that are -1/3. Those are the perpendicular lines.
