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

If h(x) = x2-5x + 7 find:
⅓ h(-8)
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]

Answer: 45 units
Step-by-step explanation:
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

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?
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 6600/6 = 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
