What would you like me to help you with?
Answer:
A
d = 2
Step-by-step explanation:
<em><u>Formula</u></em>
l = a + (n - 1)d
<em><u>Givens</u></em>
n = 10
a = - 5
l = 13
<em><u>Solution</u></em>
13 = - 5 + (10 - 1)d Substitute
13+5 = -5+5 + 9d Add 5 to both sides
18 = 9d Divide by 9
18/9 = 9/d
d = 2
Answer:
Step-by-step explanation:
Hello, first we can develop (x+a)(x+b)
We know that this should be equal to
So, we can identify the coefficients of the like terms
1 = 1 (terms in
1 = a + b (terms in x)
-72 = ab (constant term)
72 is 8 * 9 so, -72=9*(-8)
and we have 9 - 8 =1
so, a = 9 and b = -8
Thank you
