Answer:

A.) (7t³ + 2k^4)(7t³ - 2k^4)

Step-by-step explanation:

This is what we call a conjugate binomial which is two binomials with similar terms but with one of those terms with different signs, this shows a result of the first term squared minus the second term squared.

The formula for conjugate binomials are:

(a+b)(a-b)= a^{2}-b^{2}

In this case the multiplication of

(7t³ + 2k^{8})(7t³ - 2k^{8} )= 49 t^{6} + 14k^{4}t^{3} - 14k^{4}t^{3}  - 4k^{8}

After substracting the second and the third term you are left with:

49t^{6} - 4k^{8}

Answer:

A.) (7t³ + 2k^4)(7t³ - 2k^4)

Step-by-step explanation:

Factor the following:

49 t^6 - 4 k^8

49 t^6 - 4 k^8 = (7 t^3)^2 - (2 k^4)^2:

(7 t^3)^2 - (2 k^4)^2

Factor the difference of two squares. (7 t^3)^2 - (2 k^4)^2 = (7 t^3 - 2 k^4) (7 t^3 + 2 k^4):

Answer:  (7 t^3 - 2 k^4) (7 t^3 + 2 k^4)

it costs $5.75 to enter an arcade and $.50 to playing arcade game. You have $7.25. Right in equation that represents the number
Ksju [112]

5.75+3(.50) because it’s 5.75 and then add .50 3 times to get 7.75. Meaning you can play 3 games...

Hope that helps

Answer:

0.67

Step-by-step explanation:

Formula: k = y/x

k = 2/3

k = 0.66666666666

k = 4/6

k= 0.66666666666

k = 6/9

k = 0.66666666666

k = 8/12

Round 0.67

Hence, answer = 0.67
