A triangle has an area of 221.16 in.² the height of the triangle is 29.1 inches what is the length of the base of the triangle
Zigmanuir [339]
The formula you should use is Area = 1/2bh, in other words, area equals half times base times height. Now, substitute everything in, the equation should now be 221.16 = 1/2*b*29.1. This simplifies into 221.16 = 14.55b, now divide 14.55 on both sides, which leaves us to 15.2 = b. However, don't forget the units, which the answer (length of base) should be 15.2 in.^2.

2×-20/3 =2x help me please ​
Llana [10]

Answer:

x = - 5

Step-by-step explanation:

Given

\frac{2x-20}{3} = 2x ( multiply both sides by 3 to clear the fraction )

2x - 20 = 6x ( subtract 2x from both sides )

- 20 = 4x ( divide both sides by 4 )

- 5 = x , that is x = - 5
