Multiply (x+3)(3x+8) x times 3x =3x^2 then multiply x times 8 = 8x
keep multiplying 3 times 3x =9x then 3 times 8=24
then multiply the -3x(x+3)= -3x^2-9x
your hole expression will look like this 3x^2+8x+9x+ 24-3x^2-9x
if you need to simplify you can do by adding or subtracting them.
for example you can add 8x+9x= 17x
When the burner is off there is no energy being produced.
Once you turn the burner in it begins creating energy which is used to cook.
The answer is: newly created energy that was not present earlier.
Distributive property: a(b + c) = ab + ac
4n - 2 - 2n = 2(2n - 1 - n)
4n - 2 - 2n = 2n - 2 = 2(n - 1)
Step-by-step explanation:
the area is
length × width
increasing the length by 30% means multiplying the original length by 1.3.
increasing the width by 10% means multiplying the original width by 1.1.
so, the new area is (by using the old length and width)
length × 1.3 × width × 1.1 = length × width × 1.3×1.1 =
= old area × 1.3 × 1.1 = old area × 1.43
so, the area increases by 43%.
