21. Are the following equations conditional equations, identities, or impossible equations? a. Conditional equation
b. Identity
c. Impossible equation
4(2x-3) = &x - 12
3x +5=3x-7

4(2x-3)=8x-12 is identity

3x +5=3x-7 is impossible

Explanation:

A conditional equation is an equation that is true for some values and false for others

an identity equation is an equation that is true no matter what value you plug in

an impossible equation is an equation that has no solutions.

lets first try to solve

4(2x-3)=8x-12

distributive property, distribute the 4

8x-12=8x-12

this is an identity!

now for the second equation

3x+5=3x-7

add 7 to both sides

3x+12=3x

subtract 3x from both sides

12=0

wait a minute. This equation is false. this means it has no solutions. its an impossible equation.

Step-by-step explanation:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

the answer is 11.2 (i know i’m late)
