First one:
(3x^2+5y^2)^3
Step 1: Use the binomial theorem to expand
(3x^2)+3(3x^2)^2(5y^2)+3(3x^2)(5y^2)2+(5y^2)^3
Step 2: Simplify each term
27(x^2)^3+3(3x^2)^2(5y^2)+3(3x^2)(5y^2)^2+(5y^2)^3
Step 3: Multiply the exponents
27x^6+27x^4(5y^2)+3(3x^2)(5y^2)^2+(5y^2)^3
27x^5+135x^4y^2+3(3x^2)(5y^2)^2+(5y^2)^3
Keep going to get the final answer:
27x^6+135x^4y^2+225x^2y^4+125y^6

2nd question: (2y^3-5x)^2
Do the same thing...step by step
Answer: 4y^6-20xy^3+25x^2

Please Help, I keep getting the wrong answer every time. The length of a rectangle is twice its width. The perimeter is 60 ft. F
MrRissso [65]

Answer:

This is probably wrong. But i hope this helps anyways

Step-by-step explanation:

If the perimeter is twice its width, and the perimeter is 60. That means the whole length of the shape youre looking at is 120. (60•2) we can assume that this shape has 4 sides. 60/4.  Thats 15. So the sides are 4 ft. The length is at the top and bottom is 15. 15•4 = 60. There ya go

Explain why the absolute value of a number will never be negative
aleksandr82 [10.1K]
The absolute value of a number will never be negative because absolute value is the distance from zero, so it will always be positive. For example, you can't be -6 away from 0, you are 6 away from 0.

Given: 1 and 2 are supplements, and 3 and 2 are supplements.
Ronch [10]

The <em><u>correct answers</u></em> are:

Supplementary; ∠2 and ∠3; substitution; 2.

Explanation:

Supplementary angles are angles whose measures sum to 180°.  Thus this is the first answer.  

Since we are told that ∠2 and ∠3 are supplementary, their measures sum to 180° and they are the second answer.

We know that m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.  We can substitute "m∠2 + m∠3" for 180° in the first equation; this is the substitution property.

To isolate m∠1 on the right, we will subtract m∠2 from each side, and get that m∠1 = m∠3 and the angles are congruent.
