HELP SOMEONE PLEASE!!!!! Factor completely 10x2 + 2x − 8. 2
natka813 [3]

Answer:

2(5x - 4)(x + 1)

Step-by-step explanation:

10x^2 + 2x − 8 =

First, factor out the GCF of all terms which is 2.

= 2(5x^2 + x - 4)

5x^2 factors into 5x and x.

= 2(5x      )(x       )

-4 factors into -4 and 1, -1 and 4, and -2 and 2. Use the set of two factors in the proper positions that will give the middle term.

= 2(5x - 4)(x + 1)

Beth and her sisters are going to the state fair. Each ride costs $7, and each exhibit costs $4. The table shows the number of r
Maru [420]

Answer:

7x + 3y </=8

Step-by-step explanation:

Let x represent the number of rides Beth rides and y represent the number of exhibits she views

Each ride costs $7 to ride and each exhibit costs $3 to view

This means that x rides will cost x × 7 = $7x

Also, if she views y exhibits, the cost will be y × 3 = $3y.

Total cost of x rides and y views will be 7x + 3y

if she has at most $98 to spend at the fair, it means that all she can spend must be lesser than or equal to $98

The required expression will be

7x + 3y </=8

Find the value of c that makes the expression a perfect square trinomial x^2+22x+c with work
Yuliya22 [10]

\boxed{c=11}

<h2>Explanation:</h2>

Here we have the following expression:

x^2+22x+c

A Perfect Square Trinomial is given by the form:

(x+a)^2=x^2+2ax+a^2

So matching terms, we can conclude that:

2a=22 \\ \\ a=11 \\ \\ c=a^2=121

So, substituting c into the expression:

x^2+22x+121

It is a perfect square because:

x^2+22x+121=(x+11)^2
