Answer:
2(2x+5) (x+1) = 2(x+1)(2x+5)
Step-by-step explanation:
4x^2 +14x+10
Factor out the 2
2(2x^2 +7x+5)
2(2x+5) (x+1)
You need to keep the 2 that you factored out
2(2x+5) (x+1) = 2(x+1)(2x+5) by the Commutative Property of Multiplication
The correct answer is: [C]: " 5 " .
__________________________________________________________
→ " a = 5 " .

Explanation:
__________________________________________________________
Given: " a + 1 <span>− 2 = 4 " ; Solve for "a" ;
4 + 2 = 6 ;
6 </span>− 1 = 5 ; → a = 5 ;
To check our work:
5 + 1 − 2 = ? 4 ?? ;
5 + 1 = 6 ;
6 − 2 = 4. Yes!
So the answer is: [C]: " 5 ".

→ " a = 5 " .

Amount of money Mr Jack had:- $128
amount of money the man gave back:- $22
amount of money Mr Jack have now :- $106
amount of money the man has now :- 128 - 22
= 128 - 106
= 22
Answer :- $22
Answer:
x^2 + 3x - 18
Step-by-step explanation:
In order to solve this problem, I recommend using the FOIL method.
F = Front
O = Outer
I = Inner
L = Last
Start by multiplying the fronts which is x with x, which will give you x^2 (X to the second power).
Then, multiply x and -3, which gives you -3x. (Outer)
Third, multiply 6 and x, which gives you 6x. (Inner)
Finally, multiply 6 and -3, which gives you -18. (Last)
Now, there are like terms in the products that we just did which is 6x and -3x combine them together and you will get 3x.
So your results should be
x^2 + 3x - 18
Hope this helps!
