Find the value of x when the area of a triangle is 22 in2 and has a base of 3x-1 and height of x.
Virty [35]
The formula for the area of a triangle is (1/2)bh = A
when we plug in the numbers, we get (1/2)(3x-1)x = A
using the distributive property we get (1.5x - .5)x = A
Then its 1.5x^2 - .5x = A
then if we factor out 0.5x we get 0.5x(3x-1) = A
then with the zero product property, 0.5x can equal 0 and x would need to equal 0.
if 3x-1 = 0 , then 3x = 1 then x = 1/3. so our answer would be 1/3 I'm pretty sure because a length cannot be 0

A company paid $48 for 2 cases of printer paper. Each case contained 12 packages of paper. Next month the company’s office manag
il63 [147K]
Since 2 cases = $48

÷ 48 by 2 to get the cost of one case of paper

48÷2=$24 per case
and each case has 12 pack of paper

so $24 for 12 packs of paper

180÷12=15, which gives you the number of case you need

15 cases × $24= $360 for 180 packs
