Simplify the expression below.
3 · -8 + 5 - 4 ÷ 2
a-11.5
b-21
c-12.5
s-27

B. -21

Step-by-step explanation:

You have to follow PEMDAS

3*-8=-24

So, -24+5-4÷2

-4÷2=-2

So, -24+5-2

Then add and subtract from left to right

-24+5=-19

-19-2=-21

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

true
