Answer:

Option (A)

Step-by-step explanation:

2x² + 5x - 8 = \frac{5}{2}x + 20

2(2x² + 5x - 8) = 2(\frac{5}{2}x+20)

4x² + 10x - 16 = 5x + 40

4x² + 10x - 5x - 16 - 40 = 0

4x² + 5x - 56 = 0

By using graphing calculator,

x - intercepts are,

x = -4.4 and x = 3.2

Therefore, Option (A) will be the correct option.

What is 3x3-45 divided by (4+1)
Lorico [155]

Answer:

3x3-45÷(4+1) is 0.

Step-by-step explanation:

We have to do order of operations so we follow PEMDAS:

P is for Parentheses so we do what's in parentheses first:

(4+1)=5

E is for Exponents but we don't have exponents.

Next is M and D for Multiplication and Division. We have division before multiplication so we should do division first:

45÷5=9

We now have multiplication:

3x3=9

Now we have A and S for addition and subtraction

We don't have addition so we'll do subtraction:

9-9=0

The final answer is 0.

Hope this helps! :)
