Answer:
C. 70 in^2
Step-by-step explanation:
What you do is use the formula for finding the area of a trapezoid.
A=a+b/2(h).
a=8
b=12
h=7
A=8+12/2(7)=70 in^2 is your answer.
Answer:
j would be 130 cuz sides that are congruent have congruent angles so you add those two angles up and subtract from 180
Answer:
A. Use inverse relationships to "undo" the operation.
Step-by-step explanation:
I took the , and this was the correct answer. :)
Step-by-step explanation:
Area = ½ × b × h
= ½ × (7.9 + 10.8) × 6.2
= ½ × 18.7 × 6.2
= ½ × 115.94
= <u>5</u><u>7</u><u>.</u><u>9</u><u>7</u><u> </u><u>cm²</u>
So, the area of that trapezium is 57.97 cm²

You first simplify the expression using PEMDAS
-2x^3-10x^2+2x^3-10x^2+x
then combine like terms,
(-2x^3+2x^3), (-10x^2-10x^2), x
cancels out^
so the answer would be -20x^2+x
