- do not be distracted by the signs, +1 and +5 can both be written as -(-1) or -(-5) rispectively.
Answer:

Answer:
He needs to mow 8 more lawns
Step-by-step explanation:
3 lawns/ month * 7 months = 21 lawns
29 lawns - 21 lawns = 8
He needs to mow 8 more lawns
Answer:
(21, 2 )
Step-by-step explanation:
Given the 2 equations
y = - 
x + 9 → (1)
y = 
x - 12 → (2)
Substitute (2) into (1)
x - 12 = - x + 9 ( add x to both sides )
x - 12 = 9 ( add 12 to both sides )
x = 21
Substitute x = 21 into either of the 2 equations and evaluate for y
Substituting into (2)
y = × 21 - 12 = 14 - 12 = 2
Solution is (21, 2 )
Answer:
(y + 4)(y + 1)
Step-by-step explanation:
Given
y² + 5y + 4
Consider the factors of the constant term (+ 4) which sum to give the coefficient of the y- term (+ 5)
The factors are + 4 and + 1 , since
4 × 1 = 4 and sum = 4 + 1 = 5 , thus
y² + 5y + 4 = (y + 4)(y + 1) ← as a product of factors
