Answer:

The answer to the equation is 128.

Step-by-step explanation:

Simplify the following expression:

4(20+12) divided by (4-3)

4(20+12) = 4(32) = 128

(4-3) = 1

So, \frac{4(20+12)}{4-3}

= \frac{128}{1}=128

So, the answer to the equation is 128.

For the equation y = 3x2 - 4x + 11, choose the correct application of the quadratic formula.
stiv31 [10]
Starting off, if you understand the quadratic formula (if you don’t look up the formula) you’re looking for A,B, and C. A is 3, B is -4, and C is 11. You would then plug in these numbers following the quadratic formula, which results in;

The first option is the correct one. :)

Help is appreciated! :)<br>(Question is in image below)
kow [346]

Answer:

92 more miles (D)

Step-by-step explanation:

I believe the answer is 92 more miles (d). So we know that Mr Klein is driving at a steady 60 miles per hour for 42 minutes. There are 60 minutes in an hour, so every minute they've driven a mile. Therefore, in 42 minutes, they've driven 42 hours. And then 134 - 42 is equal to 92, which is your final answer.

Hope this helped!! :D

Does anyone know what the √2.25 is when rewritten as a fraction?
Zinaida [17]

Answer:  \sqrt{\frac{9}{4} }

Step-by-step explanation:

This is what it is as a mixed number

\sqrt{2.25}

= \sqrt{2\frac{1}{4} }

= \sqrt{\frac{9}{4} }

If you want it written in exponential form it would look like this:

(\frac{9}{4}) ^{\frac{1}{2} }
