Answer:  The correct option is (A) 3(x^2-7).

Step-by-step explanation:  We are given to factorize the following quadratic expression completely :

P(x)=3x^2-21.

To factorize the given expression, first we should take common terms out and then we will continue the process.

The factorization is as follows :

P(x)\\\\=3x^2-21\\\\=3(x^2-7).

Thus, the required factorized form is 3(x^2-7).

Option (A) is correct.

It's asking you to work out how many minutes it will take to drive to a school if you're driving at a speed of 35 miles per hour (mph).

But there's a problem with the question because it doesn't tell you how far away the school is.

But this is how you are supposed to do it:

Distance ÷ 35 = answer (in hours)
Answer (in hours) × 60 = Final answer (in minutes). 

It's like this because time = distance ÷ speed, and the question asks for the answer in minutes, but the unit is in miles per hour, so you multiply by 60 to get the answer in minutes.

Hope I helped :)

Solve -3x+y=7<br> please step by step :)
Scorpion4ik [409]

Answer:

x = 1; y = 10

Step-by-step explanation:

There's absolutely not enough information to find exact values for x and y with the information given, but using an example x value of 1, you can solve for y:

-3(1) + y = 7

-3 + y = 7

y = 10
