Will give a lot of points!

First: 104 gallons

Second: 26 gallons

Step-by-step explanation:

Let the quantity of the first brand be 'x'

The second brand would be '130 - x'

40%(x) + 65%(130 - x) = 45%(130)

0.4x + 84.5 - 0.65x = 58.5

26 = 0.25x

x = 104

130 - x

130 - 104

26

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
