Answer:

Your answer is 49.

Step-by-step explanation:

What you do first is you have to do the exponent in the parenthesis first.

2^2=4 so it will be (3+4)^2.

You will then add 3 and 4 together in the parenthesis to get (7)^2.

You will then square 7 to get 49 as your answer.

gizmo_the_mogwai [7]

Answer:

She need 96 square feet carpet to cover the room.

Step-by-step explanation:

Given:

Tina covers the floor of a room with carpeting. She uses carpet squares that measure one foot on each side.

Now, to find carpet squares does she need to cover a room that 8 feet wide by 12 feet long.

So, the dimensions of room are:

Length = 12 feet.

Width = 8 feet.

Now, getting the area by putting formula:

Area of room = Length × width

$Area\ of\ room = 12\times 8$

$Area\ of\ room=96\ square\ feet.$

Therefore, she need 96 square feet carpet to cover the room.

Determine the possible side lengths of the third side of a triangle with known side lengths 3 and 6. answers: –3 < c < –9

vovangra [49]

Answer:

3 < c < 9

Step-by-step explanation:

The length of a side of a triangle cannot be negative. This eliminates the first and last options.

The addition of two sides of a triangle must be greater than the third side. In this case:

3 + 6 = 9 > c

So, the second option is correct. The third option is not correct, because, for example, c = 8 is possible

Answer:

Step-by-step explanation:

The trick here is to reduce each of the bases to lowest form first

$12 = 3.4 = 3 .2.2 = 3.2^{2}\\12^{3} = (3.2^{2} )^{3} = 3^{3}2^{6} \\6 = 3.2\\6^{5} = (3.2)^{5} = 3^{5} .2^{5} \\\\Numerator = 3^32^63^52^5 = 3^82^{11}\\Denominator computation\\9 = 3^2\\9^{4} = (3^{2} )^4 = 3^{8} \\Denominator = 3^82^{10} \\\\\frac{Numerator}{Denominator } =\frac{{3^8}{2^{11} }}{3^82^{10}} = \frac{2^{11}} {2^{10}} = 2^1 = 2$
