Factor 6x4 â€"" 5x2 12x2 â€"" 10 by grouping. What is the resulting expression? (6x 5)(x2 â€"" 2) (6x â€"" 5)(x2 2)
vitfil [10]

Polynomial equation is an expression of two or more algebraic terms, which are added or subtracted from each other to form an equation. The resulting expression given polynomial function is,

(6x^2-5)(x^2+2)

Hence, option 4 is the correct option.

<h3>Polynomial- </h3>

Polynomial equation is an expression of two or more algebraic terms, which are added or subtracted from each other to form an equation.

The power of the variable is different but has the same variable.Given-the given polynomial equation is,

6x^4-5x^2+12x^2-10

Rearrange the given equation, we get,

6x^4+12x^2-5x^2-10

6x^2(x^2+2)-5(x^2+2)

(x^2+2)(6x^2-5)

(6x^2-5)(x^2+2)

Thus, the resulting expression given polynomial function is,

(6x^2-5)(x^2+2)

Hence, option 4 is the correct option.

The area of a triangle is 15 square inches
babunello [35]

Answer:

6 inches

Step-by-step explanation:

The formula for the area of a triangle is

Area = \frac{1}{2} (bh)

b - base

h - height

the first step is to add the information that we know into the formula.

We know the area = 15 inches^{2} and the height = 5 inches

15 in^{2} = \frac{1}{2} (b)(5)

if we had both the base and the height, the next step would be to multiply

b x h then half the answer to work out the area but as we already have the area (15in^{2}) we need to work in reverse.

15 x 2 = 30

what is 5 multiplied by to get 30?

5 x ? = 30

30 ÷ 5 = 6

∴ the base = 6inches

to check if our answer is correct, we can place these numbers into the formula

A = \frac{1}{2} (6)(5)

A = \frac{1}{2} (30)   (30 ÷ 2 = 15)

A = 15in^{2}

I hope this was helpful :-)

Inga [223]

It will take them 6 hours to travel 300 miles. How I got my answer: 160 divided by 3.2 = 50 miles per hour, 300 divided by 50 = 6 hours. Hope I could help! :D
