A is an angle since it is a capital letter and both b and c are sides. We also know one height of the triangle could equal b times sinA. So my height=(c+2)(sin(2c^3+16)), depending on which height we are looking for, in this case I am using c as the base.

Which expression is equivalent to - 2/5(x+0.8) + 1/50?

Rudik [331]

Answer:

-0.4x - 0.30 or $-\frac{2}{5} - \frac{3}{10}$

Step-by-step explanation:

Change all the fractions to decimals.

-2/5 = -0.4 Distribute that over x and 0.8 1/50 = 0.02

you get -0.4x -0.32 + 0.02

Change all the decimals to fractions.

0.8 is 8/10 so -2/5 times 8/10 is -16/50

-2x/5 - 16/50 + 1/50 add or subtract the fractions to get -15/50 Then reduce (÷5)

-2x/5 - 3/10
