3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169
9^2 + 12^2 = 15^2
81 + 144 = 225
225 = 225
<span>a^2 + b^2 is = to c^2</span>
2 by 7 + – is equals to 1 so we can say that x.
x=1-2/7
x=7/7-2/7
x=5/7
Hey there!
For all this, we'll start with defining any variable as "a number", as we're using words.
a) Three less than the product of five and a number.
b) Two times the sum of x and y.
c) Three subtracted from the sum of a number and five.
Hopefully this helps!
