The difference in age between Brita and her daughter Eva is 30 years. The sum or their ages 118. How old is Eva?

Alona [7]

Answer:

Eva's age is 44 years

Step-by-step explanation:

Let

x ----> Brita's age

y ----> Eva's age

we know that

The sum or their ages 118

$x+y=118$ ----> equation A

The difference in age between Brita and her daughter Eva is 30 years

$x-y=30$ ----> equation B

Solve the system by elimination

Adds equation A and equation B

$x+y=118\\x-y=30\\---------\\x+x=118+30\\2x=148\\x=74$

<em>Find the value of y</em>

substitute the value of x in any equation

$74+y=118\\y=118-74\\y=44$

therefore

Eva's age is 44 years

What is the middle term of the product of (x + 5)(x + 2)? A.7x B.10x C.18x

torisob [31]

When you use F.O.I.L. on problems you get an answer that looks like this; ax^2 + bx + c. The middle term is bx. To find this term we solve out by multiplication. so x*x + 5*x + 2*x + 5*2 or x^2 + 7x + 10, so the middle term is 7x.

If c(x)=4x-2 and d(x)= x^2+5x what is (c*d)(x)

Afina-wow [57]

$c(x)=4x-2\\d(x)=x^2+5x\\\\(c\times d)(x)\\=(4x-2)(x^2+5x)(x)\\=4x^3+20x^2-2x^2-10x(x)\\=4x^3+18x^2-10(x)$

If I understood correctly
