Your answer is D. 5 :)
Plug 5 into the place of x and we now have 5-1.
5-1 is 4.
3 to the power of 4 is 81.
Hope this helps, have a wonderful day! :)
Answer:
26 inches
Step-by-step explanation:
To find the area of a trapezoid, you must...
1) Add base 1 and base 2 together
7.5 + 5.5 = 13
2) Divide by 2
13 / 2 = 6.5
3) Multiply by height
6.5 x 4 = 26
Area = 26 inches
Answer:
B
Step-by-step explanation:
The mistake the student made in the second procedure is she tried to solve 3.7+2.6 the same way she solved 4.3+8.4, which that way doesn't always work. You have to understand how decimals work when it comes to adding them. The right way to solve 3.7+2.6 and be sure you are accurate is to line the numbers up. Then add the numbers behind the decimal which is 7+6. That equals 13. So you would out your 3 and carry your 1 over to the number in front of the decimal. So 3+2=5, plus the additional one you had to carry. Your final answer would be 6.3
Area= 1/2(base)(height)
A= 1/2(7)(2)
A= (1*2*7)/2
A= 14/2
A= 7 units squared
Hope this helps! :)
