Answer:
2666 if you multiply the sum of the parenthesis
but if you add them then the answer is 105
Step-by-step explanation:
56+6=62
40+3=43
62•43= 2666
Step-by-step explanation:
Equation (1) is :
x+2=5
Subtract 2 from both sides,
x+2-2=5-2
x=3
Equation (2) is :
2n+5=n
Taking like terms together,
2n-n=-5
n=-5
Equation (3) is :
5(x+2)-7=3x+5
⇒5x+10-7=3x+5
taking like terms together,
5x-3x=5-10+7
⇒2x=2
x=1
Hence, x =3, n = -5 and x = 1 is the required answer.
Answer:
108° and 72°
Step-by-step explanation:
let one angle be x then the other angle is 
x
the sum of the 2 angles = 180°, hence
x + x = 180 ( combining the left side )
x = 180
multiply both sides by 3 then divide both sides by 5
5x = 540 ⇒ x = 108
the 2 angles are x = 108° and x = 72°
Plug in 5x for y
x(5x) = 45
5x^2 = 45
Divide by 5
x^2 = 9
X = 3
