To find the area of the rectangle, you have to multiply the length by the width. 27 x 40 = 1,080 in ^2
Answer:
Mode: 60
Median: 30
Mean: 36.666
Step-by-step explanation:
Answer:
The answer is -16
Step-by-step explanation:
X= 39
Explanation:
4(39)+6 = 150
Answer:
area of the original square = 36 in²
Step-by-step explanation:
given data
one side is increased = 9 inches
other side is decreased = 2 inches
area of the resulting rectangle = 60 in²
solution
we consider here x as the length of any one side
and
longer side of the resulting rectangle = x + 9
and
the shorter side x - 2
so that area of this rectangle is (s+9) × (s-2) = 60 in²
standard form of equation is x² + 7x - 18 = 60 .....................1
it will be
x² + 7x - 78 = 0
(s+13) (s-6) = 0
so that here x = -13
and x = 6
here we Discard x = -13 because the side length cannot be negative.
so x = 6
and area of the original square = 36 in²
