Answer:x<-7

Step-by-step explanation:

3x -15x - 30 > 54

I moved 30 from left side to right which becomes positive and > becomes <

-12x<84

-12x/-12<84/-12           I used my calculator to do this

Which long division problem can be used to prove the formula for factoring the difference of two perfect cubes?
worty [1.4K]

Answer:

a-b  divided into a^{3} + 0a^{2} b + 0 ab^{2} - b^{3}

the reason is that the (a-b) vs (a+b) in the "SOAP"

same, opposite, always a plus the "-" in the "a-b" has to match the

sign between the two cubes

Sergeeva-Olga [200]

The <em><u>correct answer</u></em> is:

A box and whisker plot

Explanation:

A box and whisker plot, or a box plot, displays what is called the "five number summary."  This includes:

Median; LQ (lower quartile, or the median of the lower half of data); UQ (upper quartile, or the median of the upper half of data); lowest value; and highest value.

This will show the spread of data, and the mean can easily be added to this diagram.

2(6x2) + 2(6x3) + 2(2x3)

2(12) + 2(18) + 2(6)

24 + 36 + 12

The answer would be 72 ft sqaured

13. 5/6+9/11
Juli2301 [7.4K]

Explanation:

Addition of fractions can be accomplished using the formula ...

a/b + c/d = (ad +bc)/(bd)

Usually, you are asked to find the common denominator and rewrite the fractions using that denominator. It is not necessary, but it can save a step in the reduction of the final result. Here, we'll use the formula, then reduce the result to lowest terms.

___

13. 5/6 +9/11 = (5·11 +6·9)/(6·11) = 109/66 = 1 43/66

___

14. 7/20 -5/8 = (7·8 -20·5)/(20·8) = -44/160 = -11/40

___

15. 1/5 -1/12 = (1·12 -5·1)/(5·12) = 7/60

___

Dividing fractions can be accomplished different ways. I was taught to multiply by the inverse of the divisor. ("Invert and multiply.") Here, that means the problem (2/7) / (1/13) can be rewritten as ...

(2/7) × (13/1) . . . . . where 13/1 is the inverse of 1/13.

You can also express the fractions over a common denominator. In that case, the quotient is the ratio of the numerators. Perhaps a little less obvious is that you can express the fractions using a common numerator. Then the quotient is the inverse of the ratio of the denominators: (2/7) / (2/26) = 26/7. (You can see how this works if you "invert and multiply" the fractions with common numerators. Those numerators cancel.)

__

16. (2/7)/(1/13) = 2/7·13/1 = 26/7 = 3 5/7
