Answer:

Step-by-step explanation:
hey there!!!
we know already that the area of a triangle is given as

where b= base
and h= heigth
Given that the height is 5 times more than twice it base
let h= 2b+5
Now we substitute h=2b+5 in the area of the triangle


D. works because if you work it out that means 2n=140 and then divide by 2 which means n=70 and the other number is 71
To find the answer we start by adding the contents of both containers together
7.49 + 6.26 = 13.75
Since we know that there is leftover paint we are going to subtract the leftovers from the total of combined paint
13.75 - 0.43 = 13.32
The combined paint is poured into 4 containers so we divide our combined total minus the leftovers by 4
13.32/4 = 3.33
Answer: There are 3.33 liters of paint in each container
45 and 45 because they are equal and add up to 90 degrees
