# Math Help - Some stuff :P

1. ## Some stuff :P

Like this (Everything in bolded is the questions, and just give the answer. If you have time, steps too, but it is not required) :

(Write the following in algebraic expression)

Find the sum of the squares of two consecutive integers (Let the smaller integer be n.)

Brrr... brain freeze!!

The 2 adjacent sides of a rectangle are m cm and n cm. What is the total length of the adjacent sides? It is... (# cm)

$n^2+(n+1)^2$

$n+m$

3. 2 times a number plus 12 is equal to the sum of the number and 36. What is the number? I put 12... iz that right?

In 16 years, John will be 3 times as old as he is now. How old is he?

The area of this trapezium is 270 cm2 (Squared). Find its height. They give me two measurements already: 8 cm, and 28cm.

4. Two times a number ( 2X ) plus 12 is equal to the sum of that number and 36.

I think the equation should look like 2X + 12 = X + 36 then X = 24

Johns current age is unknown ( X ). In 16 years he will be 3 times X

The equation should look like X + 16 = 3X Can you get it from here?

Don't remember trapaziods.

5. The area of a trapaziod is given by the following equation

Area = Height * ((a + b)/2) Because you are given the area and you ask for the height, I would assume that the two measurements you are given is a and b

So 270 = h * (28 + 8)/2
270 = h * 36/2
270 = h* 18 divide both sides by 18 and you get
15 = h

(and why is there no equation editor here )
