Step-by-step explanation:

2x³ - 32x ← factor out 2x from each term
= 2x(x² - 16) ← difference of squares
= 2x(x - 4)(x + 4)
(29)
3x² + 6x + 3 ← factor out 3 from each term
= 3(x² + 2x + 1) ← perfect square
= 3(x + 1)²
(30)
[tex]x^{4}[/tex] - 81 ← difference of squares
= (x² - 9)(x² + 9) ← (x² - 9) is also a difference of squares
= (x - 3)(x + 3)(x² + 9)
(31)
5[tex]x^{5}[/tex] - 15[tex]x^{4}[/tex] + 10x³ ← factor out 5x³ from each term
= 5x³(x² - 3x + 2)
= 5x³(x - 1)(x - 2)

Solve the y for the equation 5x-2y=10
Answers
Answer:
y = 5/2x - 5
Step-by-step explanation:
Step 1: Write equation
5x - 2y = 10
Step 2: Solve for x
Subtract 5x on both sides: -2y = 10 - 5xDivide both sides by -2: y = -5 + 5/2xRewrite: y = 5/2x - 5Answer:
y = (5/2)x - 5
Step-by-step explanation:
5x-2y = 10
Subtract 5x from both sides
-2y = 10 - 5x
Rearrange
-2y = -5x + 10
divide both sides by -2 to isolate y
y = (5x/2) + (10/-2)
y = (5/2)x - 5

Answer: For I the answer is m=55, for J the answer is x=24
Step-by-step explanation:
I. Remote interior angles add up to exterior which means 30+80=2m which is 110=2m. Divide 110 by 2 gives you m=55
J. Same concept but this time it is 5x=120, divide 120 by 5 gives you 24.

One week, Brooklyn earned $179.30 at her job when she worked for 11 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $244.50?
Answers
Answer:
Brooklyn would get paid 16.30 hourly. So she will have to work 15 hours the next week to earn 244.50.
Step-by-step explanation:
Divide 179.30 by 11 and you would get 16.30 which is her hourly wage. Then you divide 244.50 by 16.30 to see how many hours she would have to work to earn 244.50.
Answer:
15 Hours
Step-by-step explanation:
179.30 / 11 = $16.3 an hour
244.5 / 16.3 = 15 hours

Find the value of x in each of the following
a) 2x/3= 8
b) 3x/2=6
Answers
Answer:
A) X = 12
B) X = 4
Step-by-step explanation:
For both equations, the first step is the same. You must isolate x.
A) 2x/3 = 8
Multiply each side by 3 to get rid of the fraction.
2x = 24
Divide by 2.
x = 12
B) 3x/2 = 6
Multiply each side by 2 to get rid of the fraction.
3x = 12
Divide by 3.
x = 4

What is 10 times greater than 2000
Answers
Answer:
20,000
Step-by-step explanation:
Let's take it step-by-step
10 times greater than 2,000
10 x 2 = 20, 10 x 20 = 200, 10 x 200 = 2,000, 10 x 2,000 = 20,000
just remember to add a zero after each number so, if you have 10 x 20, just take the 2 and but a zero, 20, 10 x 20 = 200, Etc.
If you need more help let me know :)
Ten times greater than 2000 is 2000.
How to find out how many times greater or less given quantities are relative to each other ?To find how much greater one quantity is to other just divide other quantity by one quantity.If how many times is given and have to find greater just multiply the given quantity by the given times.
In the given question 10 times greater than 2000 is 2000 multiplied by 10 = 20000
To reverse check divide 20000 by 2000 and the result should match the previous result you have obtained.

Answer:
-0.55 + 0.53a
Step-by-step explanation:
-0.55 – 0.47a + a
To find an expression equivalent to this, we must simplify the equation to a reasonable extent;
-0.55 – 0.47a + a
= -0.55 + 0.53a
= 0.53a - 0.55
The expression equivalent to the given one is -0.55 + 0.53a or 0.53a - 0.55
Is the following number irrational?
-8.7
Answers
Answer:
No.
Step-by-step explanation:
Rational numbers are any of the following:
Integers (positive whole numbers, negative whole numbers, or zero).Fractions e.g. 3/4Terminating (with an end) or repeating decimals e.g. 0.2 or 0.333333... or 0.343434...Irrational numbers are thus defined as:
Non-terminating (unending), non-repeating decimal numbers. e.g. π, surds ( [tex]\sqrt{2}[/tex] ).This means that -8.7 is not irrational, as it is not an unending, non-repeating number: an easy way to remember how to answer this is to look at whether the number has been expressed in decimal form if it has (unless you have been told that it has been rounded) it must be rational, as it can be written as a decimal number.
