Answer:

125-5x^2

this is the answer

Answer:

-5x^2+125

Step-by-step explanation:

You need to go step-by-step here. I would actually prefer to multiply by 5 at the end, because it's easier that way. (You can multiply the terms in any order you want, though.)

So first, multiply (5-x)(5+x). This is a special product: (a-b)(a+b)=a^2-b^2, so:

(5-x)(5+x)=5^2-x^2=25-x^2

But even if you don't know that special product, you can multiply it out. Rewrite (5-x)(5+x) as 5(5+x)-x(5+x).

 5(5+x)-x(5+x)

=25+5x-(5x+x^2)

=25+5x-5x-x^2

=25+0x-x^2

=25-x^2

As you can see, the result is the same regardless of you get it. Now multiply that by 5 to get 125-5x^2, or in standard form, -5x^2+125.

Step-by-step explanation:

Noah scored 20 points in a game. Mai's score was 30 points. The mean score for Noah, Mai, and Clare was 40 points. What was Clare's score? Show your work.
I need this answer ASAP.

Answers

Answer:

Clare's score was 70.

Step-by-step explanation:

N = 20

M = 30

C = ?

Mean = (Sum of all values)/3

40 = (20 + 30 + c)/3

40 = (50 + c)/3

50 + c = 120

c = 70

Answer:

70

Step-by-step explanation:

Let's think about this backwards. The mean of all 3 points is 40, so that is our answer. We instead of dividing would multiply. We would multiply by 3 'cause that's how many numbers there are. We would get 120. Finally, we would                                                                                                    

                                                                                      3

have to subtract. We will do this problem:

20 + 30 = 50

120 - 50 = 70

So, we get our answer of 70!

__

Let's check our work!

20 + 30 + 70 = 120 = 40

         3               3

__

Let's explain our work propproperly:

First, I took the mean and multiplied it by three because we have Noah, Mai, and Clare. Next, I added 20 and 30 to get an answer of 70 which is the answer. In conclusion, Clare's points are 70 points.

Figure A maps to figure B with a scale factor of 1 1/2.
What is the value of x?

Answers

Answer:

x = 6/2 = 3

Step-by-step explanation:

This is a dilation. A dilation is a change in size, whether it is an enlargement or reduction.

The scale factor is how much the enlargement is.

The side of Figure A is 2.

So we must multiply 2 ⋅ 1 1/2.

2 ⋅ 1 1/2 (3/2) = 6/2

6/2 is equal to 3.

Therefore, the value of x in Figure B is 3.

The length of the rectangle is twice the width.

The other vertices are located at (4, ___ ) and (10, ___ ). What could these ordered pairs be?

pls help im begging yu

Answers

Answer:

the remaining two vertices must be (4, -7) and (10, -7).

Step-by-step explanation:

The vertices (4, 5) and (10, 5) lie on the same horizontal line, y = 5.  The length of the rectangle is the difference between the two x-coordinates:  10 - 4, or 6.

Let's denote 6 as the width.  Then the length is twice that, or 12.

Then the remaining two vertices must be (4, -7) and (10, -7).

Check:  is the width 6?  Does 10 - 4 equal 6?  Yes

Is the length twice the width, or 12?  Does 5 - (-7) = 12?  YES

The other vertices are located at (4, -7 ) and (10, -7)

Area of a rectangle

Given two points on a rectangle as (4, 5) and (10, 5)

Since both coordinates lies on the same y axis, then the width of the triangle is expressed as;

width = 2(10-4)

width = 12 units

The y coordinate of the other vertices will be;

y = 5 - 12

y = -7

Hence the other vertices are located at (4, -7 ) and (10, -7)
