Answer:
6x+3
Step-by-step explanation:
you add common terms which is x+5 and x is equal to 1 so its 5+1 which is 6 and the 3 you can't add anything to it so the answer will be 6x+3
Answer:
x = 8
Step-by-step explanation:
x + 2 = 10
x = 10 - 2
x = 8
8 + 2 = 10
$185 + $545 = $730
$730 x .20 = $146
$730 - $146 = $584
FINAL COST NOT INCLUDING TAX:
$584
18.7 rounded to the nearest whole number is 19.
Answer:
15ab
Step-by-step explanation:
When you multiply out the square (p+q)^2, you get the trinomial ...
(p +q)^2 = p^2 + 2pq + q^2
Your binomial is (3a+2.5b), so you have ...
p = 3a
q = 2.5b
and the trinomial you get when you multiply it out is ...
(3a)^2 + 2(3a)(2.5b) + (2.5b)^2
= 9a^2 + 15ab + 6.25b^2
The first and last of these terms are shown on the right side of the given expression, so to finish out the identity, you need to replace * with 15ab.
