Answer:
x = 9
Step-by-step explanation:
since the terms are in AP then there is a common difference between consecutive terms, that is
a₂ - a₁ = a₃ - a₂ ( substitute values )
x - 7 = 11 - x ( add x to both sides )
2x - 7 = 11 ( add 7 to both sides )
2x = 18 ( divide both sides by 2 )
x = 9
A=bh
A=471.5(21.3)=10042.95cm2
7/8 = 87.5%
I'm guessing it is meant to say round to the nearest 10th of a percent
If the question actually says something different comment so i can fix it
Multiply 4x2 since the opposite side is the same length, and then subtract the answer (8) from the perimeter (14 units) and you’ll get 6. and then divide 6 into 2 since there is 2 more congruent sides, and you will get 3.
