What is the sum of x^2 - 3x + 7 and 3x^2 + 5x - 9
Dmitrij [34]

Hey there!

The answer to your question is 4x^2+2x-2

Given:

x^2-3x+7 and 3x^2 +5x-9

First, we can start by adding like terms. The following are like terms:

x^2 and 3x^2

-3x and 5x

7 and -9

Now, we can add these pairs together, giving us:

4x^2

2x

-2

Now, add all this together, and we get our answer as:

4x^2 + 2x - 2

Have a terrificly amazing day!

What is SV? Put the answer down below.
viktelen [127]

The measure of length SV is 60 units

<h3>Isosceles Right Triangle</h3>

An Isosceles right triangle is a right triangle that has equal opposite and adjacent sides.

The above means that:

SV = ST

Substitute values for SV and ST

2z = z + 30

Subtract z from both sides

z = 30

From the figure, we have:

SV = 2z

Substitute 30 for z

SV = 2 \times 30

SV = 60

Hence, the measure of length SV is 60 units
