Simplify the expression:
1.9b + 8.2(8.8 + 1.2b)

11.74b + 72.16

Step-by-step explanation:

In this question, we're going to simplify the expression.

Solve:

1.9b + 8.2(8.8 + 1.2b)

Use the distributive property.

1.9b + 72.16 + 9.84b

Combine like terms.

11.74b + 72.16

Since we can't simplify any further, 11.74b + 72.16 would be your answer.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
