The constant term should be (-5/2)^2 or (5/2)^2 or 25/4. This constant term comes from taking the coefficient on the x^1 term, halving it, and then squaring it.
Answer:
(a + 9)(a - 5)
Step-by-step explanation:
Given
a² + 4a - 45
Consider the factors of the constant term (- 45) which sum to give the coefficient of the a- term (+ 4)
The factors are + 9 and - 5 , since
9 × - 5 = - 45 and 9 - 5 = 4 , then
a² + 4a - 45 = (a + 9)(a - 5) ← in factored form

Step-by-step explanation:
when x = -1
y= 3x - 1
3(-1) - 1
-3 -1

when x = 0
y = 3x - 1
3(0) - 1

Answer 1:
For problem 1, each shirt can cost $15. Since their are two shirts, the price would equal up to $30. The remaining money can be the price of the athletic shoes, which is $65.
Equation: 15+15+65=95
Answer 2:
For problem 2, the pair of dress slacks can cost $55, the dress shoes can cost $100, and the and the blazer can cost $145.
Equation: 55+100+145=300

You can use the special right triangles for this equation. Since the side lengths are 3 and 4, the hypotenuse of the triangle would be 5, or you can use the equation a2 + b2 = c2, 3^2 + 4^2 = c2, 25 = c2, c=5
