Given the expression: 4x10 − 64x2

Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)

Part B: Factor the entire expression completely. Show the steps of your work. (6 points)

Answers

Answer:

Step-by-step explanation:

a) 4x¹⁰ = 2² * x¹⁰

   64x² = 2⁶ *x²

GCF = 2² * x² = 4x²

b) 4x¹⁰ - 64x² = 4x²*(x⁸ - 16)

                  =4x² *[ (x⁴)² - 4²]

                  = 4x² * (x⁴ + 4) (x⁴ - 4)

                  = 4x² * (x⁴ + 4)* [(x²)²- 2²]

SIMPLIFY THIS!!!!!
7(y - 5) + 3y = 10(y +1)

Answers

The answer is the statement is false!
7(y-5)+3y=10(y+1)
Distribute the 7 to y and -5 and distribute 10 to y and 1
7y-35+3y=10y+10
Combine like terms
10y-35=10y+10
+35 to both sides
10y=10y+45
Subtract 10y from both sides and you’re left with 0=45 which is false- so the answer would be not true or there is no answer. Hope this helps!!!
Simplifying
7(y + -5) + 3y = 10y + 10

Reorder the terms:
7(-5 + y) + 3y = 10y + 10
(-5 * 7 + y * 7) + 3y = 10y + 10
(-35 + 7y) + 3y = 10y + 10

Combine like terms: 7y + 3y = 10y
-35 + 10y = 10y + 10

Reorder the terms:
-35 + 10y = 10 + 10y

Add '-10y' to each side of the equation.
-35 + 10y + -10y = 10 + 10y + -10y

Combine like terms: 10y + -10y = 0
-35 + 0 = 10 + 10y + -10y
-35 = 10 + 10y + -10y

Combine like terms: 10y + -10y = 0
-35 = 10 + 0
-35 = 10

Solving
-35 = 10

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Candy counted to 600 by 6's, beginning with 6. Danny counted to 600 by 4's beginning with 4. How many the numbers that candy counted were also counted by Danny?

Answers

Step-by-step explanation:

If we count for both numbers up to 36, we start seeing a pattern...

Candy: 6 12 18 24 30 36

Danny: 4 8 12 16 20 24 28 32 36

Every other number in Candy's counting is also counted by Danny. So here's what we'll do:

Divide 600 by 6

600/6 = 100

This is how many numbers Candy counted overall.

Divide the result by 2.

100/2 = 50

This is how many numbers Danny counted that were also numbers Candy counted.

Answer:

50 of the numbers that candy counted were also counted by Danny.

Answer:

50

Answer:

[tex]\displaystyle \frac{1}{3} h(-8) = 37[/tex]

Step-by-step explanation:

Hi there!

[tex]h(x) = x^2-5x + 7[/tex]

First, find h(-8) by replacing all of [tex]x[/tex] with -8:

[tex]h(-8) = (-8)^2-5(-8) + 7\\h(-8) = 64+40 + 7\\h(-8) = 111[/tex]

Now, find ⅓ h(-8) by multiplying the entire expression by ⅓:

[tex]\displaystyle \frac{1}{3} h(-8) = 111 * \frac{1}{3} \\\\\displaystyle \frac{1}{3} h(-8) = 37[/tex]

I hope this helps!

Find the coordinates of R and S

R = -25

S = 20

Then just subtract them to find the distance between them.

20 - (-25) = 45.

Answer:

45

Step-by-step explanation:

First, find out the specific locations of R and S: for R, it is-25, and for S, it is 20 (use the tick marks on the x-axis).

Next, to find out the distance between R and S, be sure to add the absolute value, rather than the actual numbers.

So, ∣R∣ + ∣S∣ = 25 + 20 = 45
