488cm² is your answer
Step-by-step explanation:
the area of the composite figure=area of rectangle +area of triangle
=l×b+1/2 b×h=17×22+1/2×{22-10}×19 =488cm²
First, plug in -3 for the y value.
-3=2x²-10x
Then, add 3 to both sides.
0=2x²-10x+3
Use the quadratic equation to solve
(-b+-√b²-4ac)/2a
You get 4.68 or 0.32
You still have to check your answer to see if there is an excluded value.
Both values check.
Answer:
33.3 Repeating
Step-by-step explanation:
1. You already know that 33 is the whole number so you have 33.
2. 1/3 is converted to .3333333 so you put 33 before the decimal point
3. You get 33.3333333
Hope this helps :)
$2.25+$2.25=$4.50 Twice a week
52 weeks in a year
$4.50x52 weeks = $234
