Answer:
81 kilometers per hour
Step-by-step explanation:
8:00am to 1:00pm is 5 hours
510-105=405
405/5=81
<span>x^2+15=8x
</span><span>x^2-8x=-15
x^2 - 2 (x)(4) =-15
adding 16 on both sides
</span>x^2 - 2 (x)(4) +16=-15+16
x^2 - 2 (x)(4) + 4^2= 1
(x-4)^2=1
taking square root on bothsides x-4 = +-1
so x-4=1 or x-4=-1
x-5 or x=3
Answer:
Step-by-step explanation:
Because if you put together two trapezoids, one in a reversed position, you get a paralelogram. There the side of the parallelogram is the sum of the trapezoid bases, as in the picture.
The are of paralelogram is: A=(b+B)×h
For trapezoid, half of parallelogram:
A1=A/2=(b+B)×h/2
