Mathematics
1 answer:
nadezda [96]3 years ago
6 0

Answer:

D. 49p² - 64

Step-by-step explanation:

(7p - 8)(7p + 8)

Solving this requires the 'difference of squares' concept which states;

If (a - b)(a + b)

Then the solution must be a² - b²

Considering (7p - 8)(7p + 8) then the answer is;

(7p)² - 8² = 49p² - 64

If i got 68 correct on my math test and the total is 85 what is the score?
puteri [66]
To figure this out, you need to figure out what percentage 68 is of 85.

1. Divide 68 by 85 (Divide the % correct by the total number of questions)
2. 68/85 is .8, which is 80%

How does finding the square root of a number compare to finding the cube root of a number? Use the number 64 in your explanation
dimulka [17.4K]

Answer:

To find the cube root of a number is a bit more complicated and in our days is considered impractical, but here is a method explained. Look at the 2nd example scrolling down about 1/3 of the page

If you want to know the concept of square roots and cube roots ?

the square root of a number is that number which when multiplied by itself two times gives us that number

e.g.

√64 = x , so that (x)(x) = 64

and from our multiplication table we know that

(8)(8) = 64 , so that

√64 = 8

the cube root of a number is that number which when multiplied by itself three times gives us that number

e.g.

∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64

so ∛64 = 4

any decimal which has a repeat is rational

any decimal which does not show any repeating decimals and which is never-ending is irrational
