What’s the answer in simplified form

Mathematics
1 answer:
Schach [20]2 years ago
3 0

Answer:

Step-by-step explanation:

To solve this correctly, you need to make sure to distribute the negative onto both terms in the second parentheses.

So fully expanded, the problem would be:

2y² + 8y -7 + 3y - 3 = ?

You can easily rearrange the terms, or just do it in your head!

It would become:

2y² + 8y +3y -7 -3

= 2y² + 11y -10

Make sure you keep the terms with different variables separate! I hope this is helpful!

What two numbers multiply to get 45 but add to get -10?
goldenfox [79]
There are no two numbers that multiply to 45 but add to -10.
This is because the only numbers that multiply to get 45 are 1x45, 3x15, 5x8. None of them can add to -10 even if you make some of the numbers negative instead.

If this is a factoring problem, you may have to use the quadratic equation instead.

What is the exact volume of the cone? with a 5 ft radius and a 16 ft height
andrew11 [14]

Answer:

The volume is 418.93 ft^3

Step-by-step explanation:

Here, we want to find the volume of a cone

Mathematically, we use the formula;

V = 1/3 * pi * r^2 * h

r = 5 ft

h = 16 ft

Substituting these values;

V = 1/3 * 3.142 * 5^2 * 16

V = 418.93 ft^3
