Add (7х2 – 3x) + (5х – 6).

Masja [62]

Option C: The solution is $7x^{2} +2x-6$

Explanation:

The given expression is $(7x^{2} -3x)+(5x-6)$

We need to solution of the given expression.

The solution of the given expression can be determined by adding the two expressions.

Let us remove the parenthesis.

Thus, we have,

$7x^{2} -3x+5x-6$

Adding the like terms, we have,

$7x^{2} +2x-6$

Thus, the solution is $7x^{2} +2x-6$

Hence, Option C is the correct answer.

Find the circumference of a circle with a radius of 35 inches in terms of 7 and to the nearest tenth of an inch.

Lera25 [3.4K]

Answer and Step-by-step explanation:

The circumference formula for a circle is:

C = $2\pi r$

Plug 35 in for r (radius) and solve.

C = $(35) 2\pi\\\\C = 70\pi\\\\C = 219.9$

So, approximately 219.9 $in^2$ is the answer.
