Answer: 1) 132 and 32
<u>Step-by-step explanation:</u>
Let x represent the larger number and y represent the smaller number.
*******************************************************************************************
1)
x + y = 164 and x = 3y + 36
(3y + 36) + y = 164
36 + 4y = 164
4y = 128
y = 32 and x = 3(32) + 36
x = 96 + 36
x = 132
*******************************************************************************************
2)
x + y = 120 and ⇒ 4x = 68y ⇒ x = 17y
(17y) + y = 120
18y = 120
and
Ok thats easy divide 24 by 2
27 by 3
and
36 by4
Answer:
x^2 + 8x + 16
Step-by-step explanation:
(x + 4) (x+ 4) multiply x by x and x by 4.
x^2 + 4x
Then multiply 4 by x and 4 by 4.
4x + 16
Then combine like terms.
x^2 + 4x + 4x +16
x^2 + 8x + 16
