The numbers are 109 and 327. Hope it helps!
Answer:
The side lengths are 10 by 7
Step-by-step explanation:
The area of a rectangle is
A = l*w
70 = (x - 11)(x - 8)
FOIL
70 = x^2 -8x-11x+88
Combine like terms
70 = x^2 -19x +88
Subtract 70 from each side
0 = x^2 -19x +88-70
0 = x^2 -19x+18
Factor
What number multiplies to 18 and adds to -19
-18*-1 =18
-18-1 = -19
0=(x-18)(x-1)
Using the zero product property
x-18=0 x-1=0
x=18 x=1
But x cannot x=1 because then the side lengths would be negative
x-18 = 10
x-11 = 7
The side lengths are 10 by 7
Answer: 2p^2-p
: Quadratic Binomial
Step-by-step explanation:
B is a times b
C is also a times b
sorry im stuck on the rest
Original equations : 7x - 3y = 4 2x - 4y = 1
Set of equations #1 : 28x - 12y = 16 -6x + 12y = -3
Set of equations #2 : 14x - 6y = 4 -14x + 28y = 1
Set of equations #3 : -28x + 12y = -16 28x - 56y = 14
OK, so first step is to check all of the answer choices, one by one, and see which one is incorrect.
Set #1 : For the first equation, divide the whole thin by 4, and you get the original equation. For the 2nd equation, divide the whole thing by 3, and get the original equation, so by doing this, we know that Set #1 is equal to the original equation, therefore Set #1 is not the right answer.
Set #2 : Do the same for the first equation, find a number that is divisible by all of the numbers in the original equation & with the set #2 equations. We see that if we divide those numbers, it does not equal the original equations. Therefore, Set #2 is not equal to the original equations, so Set #2 is the right answer.
Because we see that Set #2 is correct, there is no need to check Set #3. However, if you would like to, just go through the steps again.
