Answer:
3x-526
Step-by-step explanation:
the 3x would go in the beginning. then you subtract (-4-522)= -526.
(12x + 9y) + (-2y) - (4x - 3y)
= 12x + 9y - 2y - 4x + 3y
= 12x - 4x + 9y - 2y + 3y
= 8x + 10y
A) 8x + 10y
18/3=6
12/2=6
24/4=6
30/5=6
36/6=6
Answer:
26.25 square feet
Step-by-step explanation:
Calculation to determine the area of the seat
Using this formula
Area=1/2*(b1+b2)*h
Where,
b1=8 feet
b2=7 feet
h=3.5 feet
Let plug in the formula
Area=1/2*(8+7)*3.5
Area=1/2*15*3.5
Area=26.25
Therefore the area of the seat is 26.25 square feet
Two possibilities:
28^2 + x^2 = 96^2
OR
28^2 + 96^2 = c^2
784 + x^2 = 9216
subtract 784 from both side
x^2 = 8432
Take the square root of both sides
x = 91.83 NOT an Integer
28^2 + 96^2 = c^2
784 + 8216 = c^2
10,000 = c^2
Take the square root of both sides
c = 100 HYPOTENUSE
