Answer:
I'll explain below, just follow the directions. I can't directly draw it.
Step-by-step explanation:
find the length and the width of a rectangle whose perimeter is 18 ft
2L + 2W = 18
simplify, divide by 2
L + W = 9
L = (9-W)
:
whose area is 20 square feet
L*W = 20
Replace L with (9-W)
W(9-W) = 20
-W^2 + 9W - 20 = 0
Multiply by -1, easier to factor
W^2 - 9W + 20
Factors to
(W-4)(W-5) = 0
Two solutions
W = 4 ft is width, then 5 ft is the Length
and
W = 5 ft is the width, then 4 ft
The answer is none of those because you find the median of 51 which is Q2 then the lower median is 34.5 and the upper median is 73.4 then you subtract 73.5-34.5=39
Answer:
~15.31 or 8(✓2)+4 units
Step-by-step explanation:
a²+b²=c²
16+16=c²
c = ✓32 = 4✓2
2(4✓2) + 4(1) = 8✓2 + 4 ≈ 15.31
80 because you find the area of the triangle and subtract it from the area of the rectangle to get 80
