Step-by-step explanation:

Q1, Reasonable lower limit for the number of M&M's can be done by using the rectangular prism volume formula = l*w*h

From the photo, there are about 8 M&Ms along its length, l and also 8 M&Ms along its width, w. Along height, h, there are about 14 stacking over each other.

So the number can be estimated as 8 * 8 * 14 = 896 ~1000

The answer is 1000.

Q2 Chocolate chip cookies:

First container is 11 * 6 * 3 = 198 cubic inches with 90 cookies

That gives an average of 198 / 90 = 2.2 cubic inches per cookie

Second container is 6 * 6 * 2 = 72 cubic inches with 33 cookies.

Again that gives an average of 72 / 33 = 2.2 cubic inches per cookie

The answer is 2.2.

Q3 Student numbers:

The first 4 characters are single digit number that cannot be repeated

So possible combinations are = 10 * 9 * 8 * 7

The last 2 characters are letters that cannot be repeated

So possible combinations are = 26 * 25

Total number of unique student numbers = 10 * 9 * 8 * 7 * 26 * 25

= 3,276,000

Q4 TV size goes by its diagonal

So it is sqrt(32^2 + 18^2)

= 37"

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
