Answer: 34 in^3
Step-by-step explanation:
Surface area of triangle = 1/2 x 3.4 x 2.5 = 4.25
To find the volume of the prism, multiply the surface area of the triangle by length.
So 4.25 x 8 = 34 in^3

Step-by-step explanation:
If one is moving towards the other at 30, and the other by 20 more, then the equation would be 30+50, so 80mph.
Answer:
a. 10√2
Step-by-step explanation:
hey, just use Pythagoras theorem
h²=p²+b²=10²+10²=100+100=200
h²=200, h= √200 =√(100×2)=√100×√2=10√2
Answer:
The dimensions are (7m-3) by (7m-3)
Step-by-step explanation:
We have the area of the rectangular field to be:

We need to factorize this expression.
Let us rewrite to obtain:

We can easily see that the expression is actually a perfect square trinomial.
This gives us:

Or
