Mathematics
1 answer:
MatroZZZ [7]3 years ago
6 0

Answer: F

Step-by-step explanation:

This is basically like 2 rectangles. Find the area of both and add them together.

Remember that the area is l x w.

Area of Rectangle 1: l = 7, w = 14

14 x 7 = 98cm^{2}

Area of Rectangle 2: l = 5, w = 14

14 x 5 = 70cm^{2}

Add the areas together: 98cm^{2} + 70cm^{2} = 168cm^{2}

How do functions work? Could someone explain how to know which questions are functions or not
belka [17]

Answer:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a speceified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x  equals 2.

Step-by-step explanation:

here is a step by step equation:

f(x) = x + 7

if:

x=2

then:

f(2) = 2 + 7 = 9

A function is linear if it can be defined by

f(x) = mx + b

Makes sense? Hope I helped

plus I'm in middle school learning this also.

Area of a rectangle with a width of 36cm and a perimeter of 80cm
grandymaker [24]

The area would be 144cm^2.

In order to find the area, we need to know the length of the rectangle. We can find that using the perimeter formula.

2l + 2w = P

2l + 2(36) = 80

2l + 72 = 80

2l = 8

l = 4

So now that we know the length is 4, we can find the area using that formula.

A = lw

A = (4)(36)

A = 144
