7x+2y=-17
steps:
x=2x + 5x
y=3y - y
sum=-5 -12
The 3 in "513" is only 3. it's 1, 2, 3. If we do 3 x 10 it's 30

V = πr²h
3.14 × 14² × 72
The answer is 24.
8 + 8 + 4 + 4 = 24
Answer:
(y - 2)(y - 6)
Step-by-step explanation:
To factorise
Consider the factors of the constant term (+ 12) which sum to give the coefficient of the y- term (- 8)
The factors are - 2 and - 6
since - 2 × - 6 = + 12 and - 2 - 6 = - 8, hence
y² - 8y + 12 = (y - 2)(y - 6)
