17) The wording is not the best, but they want you to do 1/2 + 1/4, which is 3/4.

18) a). vertixes are the pointy bits, the ones at the angles of the faces, and edges connect vertices (count them: there are 8 vertices and 12 edges). Imagine going from one edge to the one farthest from it. If you have playdoh or some breadto cut, try it. You'll see that the section you'll obtain is a rectangle, if what you cut looks like the figure.

The door to the clubhouse has an area of 1792 square centimeters. If the length of the door is 56 centimeters , how wide is it

fomenos

Solutions

The door to the clubhouse has an area of 1792² centimeters. The length of the door is 56 centimeters. To solve the problem we need to know how to find area.

A door is in a shape of a rectangle. To calculate area of a rectangle you need to do --

L x w = area

L (56) x n = 1792

1792 ÷ 56 = n

n = 32

Check your work

L x w = area

(56) x (32) = 1792

We are correct.

The width of the door is 32 centimeters.

It will be worth about £885.59.

Step-by-step explanation:

The art piece originally costs £600.

And it appreciates at a rate of 3.97% each year.

And we want to find the value of the art after 10 years.

We can write an exponential function to model the situation. The standard exponential function is given by:

$f(t)=a(r)^t$
