Identify describe and extend each pattern 64,55,46,37,28,19

Answers

Answer 1
Answer: you subtract 9 each time. 10, 1, -8, -17, -26
Answer 2
Answer: You are subtracting 9 each time, or, if you are a visual learner, an easier way to understand it could be that the left digit always goes down 1 and the right digit goes up 1. So because of the found pattern, the next numbers would be 10...1...-8...-17...-26...-35...-44...-53... And so on. Something to remember is that when you start getting into the negative numbers, the visual pattern goes vice versa. The left number goes up 1, and the right number goes down 1, when there are negative numbers. Whereas for positive numbers, left goes down 1, and right goes up 1. If you don't get what i am saying, stare at it long enough and you'll then understand what I am meaning lol. Hope I helped!! Rate five and mark brainliest if you don't mind!!

The width of the Ochoa Community Pool is 20 feet . The length is twice as long as its width. What is the perimeter of the pool?

Answers

Answer:

The perimeter of the pool is 120 feet.

Step-by-step explanation:

width of the Ochoa community pool  = 20 feet  

length is twice as long as its width = 2(20) = 40 feet  

Use this formula to get perimeter = 2(w) + 2(L)

then the perimeter equals to  = 2(20)+ 2(40)

= 40 + 80 = 120 feet

The perimeter of the pool is 120 feet.
the width is 20 feet the length is 20 feet x 2 = 40 and I bet you know how to work out the perimeter add all the width and length so 20 + 20 +40 + 40 =120 120 feet is the answer your welcome

What is the volume of a cube with a side of length 13 units?A. 39 cubic units
B. 78 cubic units
C. 169 cubic units
D. 2197 cubic units

Answers

I think the volume of a cube with the side of length 13 units is D, 2197. This is because 13x13x13=2197. That is my answer, hope I helped! :D
(d) 2197 cubic units
v=a*a*a
v=13*13*13
v= 2197

Problem A: (7x^2-x-2)-(-6x^3+3)

You can consider the subtraction similiar to a -1(-6x^3+3). The 1 is implied. So to distribute that negative, we multiply this out.

-6x^3+3 becomes 6x^3 - 3

Our problem is now: 7x^2-x-2 + 6x^3 - 3

Now we add together like items. Let's rearrange for our sanity.

+ 6x^3 + 7x^2 - x - 2 - 3

Simplify: 6x^3 + 7x^2 - x - 5

Unfortionately, outside of factoring or something along those lines, that's as simple as we can get it. So the answer is A.

Problem B: f^2*f^4

Math rules tell us when we multiply the same bases with exponents, we add the exponents together. But the base doesn't change.

4+2 = 6. So: f^6 (D)

That's the easy answer: Math rules say so.

To expand on that specific rule, consider x^2 * x^3. What at the root are these saying? Multiply 2 copies of X, and then multiply 3 copies of x.

We can rewrite this same equation as x*x * x*x*x. 

Remember that since all of these are multiplication, there is no order of operations that needs to be followed.

If we were simplifying that version of the equation, we would write x ^ 5.
