Let P = percent of discount
(290-188)/290 = P/100
102/290 = P/100
290P = (102)(100)
290P = 10,200
Solve for P to find your answer.
Formula for P: P = 2W + 2L
Formula for A: A = WL
Here, P = 2(4 ft) + 2(7 ft) = (8+14) ft = 22 ft
and A = (4 ft)(7 ft) = 28 ft^2
Answer:
P= 3
Q= -14
R= -5
Step-by-step explanation:
Just solve the equation on the right side, you'll get:
=3x^2 -15x +x -5
=3x^2 -14x -5
Now compare it to the equation on the left side,
The coefficient of x^2 on the left is "p", on the right that we just solved is 3.
Same for "q" which is the coefficient on the left, on the right it's -14.
And for "r" it's -5 from the equation on the right.
Let n be a side of the square. Then:
n²=36
n=√36=6 cm.
