Hi! i need help
(It is due in a few hours)

1a and 2a

Step-by-step explanation:

In the first one, you should write an expression to help you picture what is happening. Since a test score is 4 times a quiz score which is x, a test score will be 4x. And since there are also 2 quizzes we should do 2x or just x + x. We then add the test score points and the quiz score points.

Here is the first way:

4x + 2x = 6x

Here is the second way:

4x + x + x = 6x

6x is your answer!

In the second one, you should also write an expression. Since a novel costs 6 more than a textbook which is represented by x, we will represent it the cost of a novel like this: x + 6. And since there is also one textbook we will just mark that as x. Now all we need to do is add them up/

This is what it will look like:

x + 6 + x = 2x + 6

2x + 6 is your answer!

I hope this helped! Please give Brainliest.

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
