(x^m)^n=x^(mn)

ok so

(3^2)(2a)^(3/2))^2=
(3^2)(2a)^((3/2)*2)=
(3^2)(2a))^(6/2)=
(3^2)(2a)^3=
(3^2)(8a^3)^3=
(9)(8a^3)=
72a^3

It is similar to division because when you reduce 14:2 you just divide 14 by 2 and 2 by 2

What is 0.78 divided by 3.51??? (Decimals)

Answers

0.78/3.51 = 0.222
The 0.222 repeats on forever, but writing it to the thousandths spot is generally an acceptable spot to stop writing the repeating number. If you're writing it on paper, put a line above the last number (or sets of numbers) that repeats. So, in this case, the last 2 in 0.222 would have a line above it, kind of like an upside-down underline, I guess.

What is the surface area of the prism?A.
144 in2

B.
420 in2

C.
288 in2

D.
140 in2

I really don't know where to post a link to the prism pic

Answers

If you want to find the surface area of something and it doesn't have a formula, just look at the area of each side individually and add them up!

The area of a triangle is equal to bh/2 = 16*6/2 =  48 in²
The area of the other triangle would be the same = 48 in²
The lateral side that's 10 by 9 inches = 10 * 9 = 90 in²
The other lateral side that's 10 by 9 is also = 90 in²
The lateral side that's 16 by 9 inches = 16 * 9 = 144  in²

144 + 90 + 90 + 48 + 48 = 420 in²

The area of the prism is 420 in. You just have to add 144 + 90 + 90 + 48 + 48 which is equal to 420 in². You just had to add the sides

Hope it helps :)

According to the given information, quadrilateral RECT is a rectangle. By the definition of a rectangle, all four angles measure 90°. Segment ER is parallel to segment CT and ______________ by the Converse of the Same-Side Interior Angles Theorem. Quadrilateral RECT is then a parallelogram by definition of a parallelogram. Now, construct diagonals ET and CR. Because RECT is a parallelogram, opposite sides are congruent. Therefore, one can say that segment ER is congruent to segment CT. Segment TR is congruent to itself by the Reflexive Property of Equality. The Side-Angle-Side (SAS) Theorem says triangle ERT is congruent to triangle CTR. And because corresponding parts of congruent triangles are congruent (CPCTC), diagonals ET and CR are congruent.
