The area of the rectangle is (2x + 3)(2x - 3) = 4x2 - 9.
Answer:
Yes , i agree with Noah that the equation would be 3(x + 7) = 57
Step-by-step explanation:
P.S - The exact question is -
To find - Noah writes the equation 3 (x+7)=57 to represent the situation.
DO YOU agree with him? Explain your answer.
Proof -
Yes , i agree with Noah
Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .
Because 57 is divided into x 7 x 7 x 7
∴ we can write it as
3 times x + 3 times 7 = 57
⇒3(x) + 3(7) = 57
⇒3(x+7) = 57
Ans Noah give the same equation 3 (x+7)=57
So, I agree with Noah.
Answer:
x=5.333
y=3
Step-by-step explanation:
given, y=5-2............(1)
1-3x+y=-12...............(2)
y=5-2=3
put y=3 in equ (2)
1-3x+3=-12
1+3+12=3x
3x=16
x=
x=5.333
hence, x=5.333
y=3 answer
Answer:
The answer is 11/8 or 1 3/8
Step-by-step explanation:
First, you can break both fractions down into 3+1/4-1+7/8.
Second, use 3 subtract 1, you will get 2+1/4-7/8.
To subtract 7/8 you have to make both numbers denominator same.
1/4 will multiply by 2 on the top and the bottom.
After that, you will get 2 2/8-7/8.
2x8=16, 16+2=18
18/8-7/8=11/8 or 1 3/8
I know its gonna be confusing, but this is all I can do, sorry about that. :)
