(X-5)(2x+3)=x(2x+3)-5(2x+3)
=x*2x+3*x-5*2x-5*3
= 2x^2+3x-10x-15
=2x^2-7x-15
Terms are: 2x^2. ; -7x. ; -15
Answer:
Alice-4
John-8
Dad-40
Step-by-step explanation:
1) using the information we know if j is John's age and a is Alice's age and d if dad's age:
2a=j
d=5j=5(2a)=10a
(a+2)+(d+2)+(j+2)=58
2) substitute the d and j for the equivalent terms using a so there is only one variable, Alice's age:
(a+2)+(10+2)+(2a+2)=58
3) combine like terms and isolate the variable and you should get your answer.

<em>12</em> <em>5</em>
Step-by-step explanation:
To solve this, you either need x or y. So x or y can be the missing values. The most you can do is simply move one of the terms to the other side.
