Well, there are two solutions.
Add both sides by 15.75 then from here, you can use quadratic formula.
So your answer should be x = -2.44949 or 2.44949.

Answer:
L = 20 inches
Step-by-step explanation:
w = width
L = length
area = 120
W x L = 120
L - 8 = 2W then L = 2W + 8
substitute for L:
W x (2W + 8) = 120
2W² + 8W -120 = 0
(2W - 12)(W + 10) = 0
2W-12 = 0
2W = 12
W = 6
L = 20
Answer:
21
Step-by-step explanation:
all you have to do is get 70% of 30
70% of 30 is 21
Answer:
Answer: x= -6 and y= -7
Step-by-step explanation:
Substitute 2x+5 for y in y=3x+11:
y=3x+11
2x+5=3x+11
2x+5+−3x=3x+11+−3x(Add -3x to both sides)
−x+5=11
−x+5+−5=11+−5(Add -5 to both sides)
−x=6
−x−1=6−1(Divide both sides by -1)
x=−6
Step: Substitute −6 for x in y=2x+5:
y=2x+5
y=(2)(−6)+5
y=−7(Simplify both sides of the equation)
