Answer:
Step-by-step explanation:
Let the larger number = x
Let the smaller number = y
x = 2*y + 8
x * y = 234 Put the first equation into the second.
(2y + 8)*y = 234 Remove the brackets
2y^2 + 8y = 234 Subtract 234 from both sides
2y^2 + 8y - 234 =0 Factor out 2
2(y^2 + 4y - 117) = 0 Divide by 2
y^2 + 4y - 117 = 0
(y + 13)(y - 9)
y = 9 is one answer
x * y = 234
x * 9 = 234 Divide by 9
x = 234/9
x = 26
The two numbers are 9 and 26
Answer:
(3a - 4 )^2
Step-by-step explanation:
(9a^2-24a+16)=(3a - 4 )^2
Therefore the length of each side of the square is (3a - 4 )^2
Answer: The answer is 16+4x
Step-by-step explanation:
4*4 is 16 and 4*x is 4x since I can't add them together it would be 16+4x
Answer: the false statement is c
Step-by-step explanation:
The graph of the amount earned for number of lawns mowed versus number of lawns mowed is sketched in the attached photo.
From the graph,
a) Money earned is graphed on the y-axis
b) The slope of the line can be used to estimate how much money Jared earns per lawn
d) Jared graphed the number of lawns mowed on the x-axis
The false statement is
c) Jared earns on average 14 dollars per lawn
I think the correct answer is b. If you divide the price by how many, you would get the price for one.
Hopefully this helps!
