1, 4, & 5 are quadratic expressions in vertex form
Step-by-step explanation:
To solve the problem
we first use the distributive property, which means to multiply everything on the inside with the outside number on the left.
so
This would equal
its pretty simple.
what may be confusing is the fraciton multiplication
to solve this we convert the -8 and -12 into a fraction. This would be
and multiplying fractions is easy, u just do it straight across.
so 3 times 8 is 24 so this would be 24/4
and 24/4 simplified is 6
and 3 times 12 is 36
so it would be 36/4
this would equal 9 simplified
and since we are just multiplying all negative numbers here they all turn out to be positive numbers because you should know. a negative times a negative equals a positive.
The answer is c!!!!!!!!!!!!!!!!!!
