what’s the answer??

Answer:Volume

Quantity of three-dimensional space

Step-by-step explanation:
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface. For example, the space that a substance (solid, liquid, gas, or plasma) or 3D shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre

Answer:

3(x²−4x+7)

Step-by-step explanation:

Factor 3x2−12x+21

3x2−12x+21

=3(x ²−4x+7)

Answer:

Step-by-step explanation:

If the polygons are similar, this means that the ratio of their corresponding sides are equal. This ratio is what we commonly refer to as the scale factor. The ratio of the area of similar polygons is equal to the SQUARE of SCALE FACTOR. For this item since the scale factor is 2, the ratio of the areas is equal to 4.

Answer:

2nd choice

When looking for common factors we are looking for the prime factors that are in common and then multiplying the prime factors together to get the GCF.

Step-by-step explanation:

The picture shows the choice that is being used to find the GCF.

sorry if im wrong

Answer:

√X2-X1+√Y2-Y1

=√7-(-9) +√-10-8

=√16 + √-18

=4 + -(√18)

=4 + (-3√2)

=-0.24

Step-by-step explanation:

by answering this you must use the distance formula and label -9 as X1 , 8 as Y1 and 7 as X2 , -10 as Y2 then you put X2-X1 in the same root sine do the same at Y2-Y1.

please mark me as as pleaseWhen two lines intersect, the opposite (X) angles are equal. In the diagram above, the two green angles are equal and the two yellow angles are equal. These X angles are called vertically opposite angles because they are opposite each other at a vertex.

Your question is...?

Answer:

1.5+1.2=2.7

2.7÷2=1.35

1.35=dad's height

Answer:

[tex]13\frac{5}{6}[/tex]

Step-by-step explanation:

[tex]\frac{60}{6}=10[/tex] (low estimate to make later estimates easier)
[tex]10+\frac{24}{6} =14[/tex] (high estimate, must make lower)
[tex]14*6\neq 83[/tex] (incorrect estimate)

[tex]84-83=1[/tex] (correcting estimate)

[tex]14-\frac{1}{6} =13\frac{5}{6}[/tex] (corrected estimate)

Answer:

10°

Step-by-step explanation:

Since 90° makes a right angle, you do 90-80, to get 10.

Answer:

[tex]\huge\boxed{\bf\:(x + 2y)^{2} - 3}[/tex]

Step-by-step explanation:

[tex]x ^ { 2 } +4xy-3+4y ^ { 2 }[/tex]

Rearrange the terms.

[tex]x ^ { 2 } +4xy+4y ^ { 2 } - 3[/tex]

Here, x² + 4xy + 4y is in the form of the algebraic identity ⟶ x² + 2xy + y² = (x + y)². Then, here, x = 1 & y = 2y.

[tex](x + 2y)^{2} - 3[/tex]

Leave 3 as it is as 3 can't be further simplified. So, the final answer is:

[tex]\boxed{\bf\:(x + 2y)^{2} - 3}[/tex]

[tex]\rule{150}{2}[/tex]

Answer:

[tex] - \frac{1}{6} [/tex]

Step-by-step explanation:

[tex] - \frac{1}{2} + \frac{1}{3} = - \frac{1}{6} [/tex]

hmmm if we take the whole area of the rectangle, well the rectangle is a 6x5, so the whole of its area is 6*5 = 30 in².

now, we have a circle inside, it really doesn't matter if it's in the center or corner so long is inside, hmmm well, we know it has a radius of 1, so let's get the area of the circle, and then subtract that area from that of the whole rectangle, by subtracting it we're in essence making a whole in the rectangle's area and what's leftover is the shaded region, that part that was not subtracted.

[tex]\stackrel{\textit{\Large Areas}}{\stackrel{rectangle}{(6)(5)}~~ - ~~\stackrel{circle}{\pi (1)^2}}\implies 30~~ - ~~\pi \implies 30~~ - ~~3.14\implies 26.86[/tex]
