Ella is solving the equation (x+5)2=0 . She writes that the solutions are x=5and−5 .

Anne looks at her work and disagrees. She says that only x=−5 is a solution. Who do you agree with? Explain your reasoning.

Answers

Answer 1

Answer:

Anne

Step-by-step explanation:

Let's solve it by replacing x by 5, then -5.

(5+5)2=0

10*2=0

20=0

(-5+5)2=0

-5 and 5 cancel each other out, and 0 times anything is 0.

0=0

So Anne is correct.

PLEASE HELP!!! Area of trapezoids and triangles ​

Answers

i want to believe 30...?

Answer: 54 square inches and 18 square inches

Explanation:

The formula for the area of a trapezoid is the sum of the top and bottom bases divided by 2, multiplied by the height.

In the first picture the bases are 6 and 12, and the height is 6, so the formula would look like this:

[tex]\frac{6+12}{2} *6[/tex]

=[tex]\frac{18}{2} *6[/tex]

=[tex]9*6[/tex]

=54

54 [tex]in.^{2}[/tex] is the answer to the first problem.

Following the same method, we can do the next problem the same way:

[tex]\frac{4+8}{2} *3[/tex]

=[tex]\frac{12}{2} *3[/tex]

=[tex]6*3[/tex]

=18

18 [tex]in.^{2}[/tex] is the answer to the second problem.

Option #2: 32 ÷2

Step-by-step explanation:

Take Note: There are 2 cups in a pint.

Since we are converting cups TO pints.... the number should (logically) be smaller. That eliminates the last two options.

Referring back to our note, it is only sensible to eliminate the first option since there are only 2 cups per pint, NOT 4.

In the end, you should have gotten option 2 which is 32÷2.

13. Jessica has taken 8 quizzes. The mean of her scores is 92. Her first 6 scores are shown.
96, 90, 88, 92, 94, 90
If Jessica got the highest score possible on her seventh quiz, what score did she get on her
eighth quiz? What would be her median score Show your work and explain your reasoning.

Answers

Answer: Median= 91; 8th quiz score=86

Step-by-step explanation: The sum of the scores is 8×92=736. Subtract the 6 given scores and then a 100 for the seventh quiz to find the score she got on the 8th quiz, this is an 86. Now that you have all the scores, arrange them all in the least to greatest order and find the average of the middle two numbers (median), which is 91!

How many solutions can be found for the equation 5x + 3(x − 1) = 10x − 2x − 3?

Answers

Answer: Infinite many solutions

Step-by-step explanation:

Given

5x+3(x-1)=10x-2x-3

Expand Parenthesis

5x+3x-3=10x-2x-3

Combine like terms

8x-3=8x-3

Subtract 8x on both sides

8x-3-8x=8x-3-8x

-3=-3

Add 3 on both sides

-3+3=-3+3

0=0

Any number will work on both sides, therefore, there are infinite solutions
