Step-by-step explanation:
Answer:
19.65 left
Step-by-step explanation:
The total amount that he has is 3 * 12 = 36 dollars.
From this he buys a CD for 15.00
There is a 9% tax on 15 dollars 15*9/100 = <u> 1.35</u>
Amount spent = <u> 16.35</u>
Amount left 19.65
Area of triangle roof:
= 1/2 (3.5)(1.2)
= 2.1 m^2
Area of large rectangle:
= 3.5 x 2.5
= 8.75 m^2
Area of small rectangle (door):
= 1.5 x 2
= 3 m^2
Total area:
= 2.1 m^2 + 8.75 m^2 +
= 13.85 m^2
<span>Which of the following statements is TRUE?
</span>b. An equation that is an IDENTITY has one solution.
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
