<em>parallelogram</em>
1. perimeter 10(2)+10(2)=32+20
perimeter = 52cm
area=b times h
area = 16(9)=144cm2
2 <em>TRAPEZOID</em>
<em> </em>perimeter =( 21+24+25+44.67)m
=114.67m
area= 1/2( b1+b2)h
1/2(44.67+25)20
696.7m2
3. perimeter = 2+3+12+2+3+5+3+2+9+7+3
=51<u>cm</u>
area = 54+6+6+6=72cm2<u> </u>
4. perimeter is 10+4+2+3+ 2+4+10+23 = <u>58cm</u>
<u>area is </u>
(11+23).8=37.8
=272
trap-rect=136-6

16.6 with a line on top of 6. When you divide 50 by 3 you get 16.6 a repeating decimal.you would round and get 17. I think it's correct!!
Answer:
see the explanation
Step-by-step explanation:
Let
x ------> the next grade
we know that
To find the average grade sum the grades by the number of math test
so
solve for x
Combine liker terms in the right side
Multiply by 5 both sides
Subtract 372 both sides
-----> this is not make sense
The grade cannot be a negative number
so
For x=0
The minimum average grade is
Answer:
x=2, y=-1
Step-by-step explanation:
Remember: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. Then, go from there.
