Make all a and constant number in different side
10-7=16z-7z+2z
3=11z
z=3/11
Answer:
A. (6x + 7)(6x - 7)
Step-by-step explanation:
use difference of squares, which says a^2 - b^2 =(a+b)(a-b)
take the square roots of the two numbers, 6x and 7, and use them as a and b
Answer:

Step-by-step explanation:
Given the equation

Use distributive property:

Use commutative property to rewrite the equation:


Add 10 th both sides:

Subtract 

Divide by 13:

First you substitute in the values so you have
V^2=(64)20
then you just simplify it
V^2=1280
V=the square root of 1280
V= about 35.7770876
or
V=the square root of 256 times <span>the square root of 5
V=16 times </span><span>the square root of 5
also V would typically be called velocity. it's very similar to speed but it is just easier to remember because it starts with a V</span>
