Answer:
15u^3 + 8u^2 - 6u + 13
Step-by-step explanation:
(7u^3 + 8u^2 + 8) + (8u^3 - 6u + 5)
= 7u^3 + 8u^2 + 8 + 8u^3 - 6u + 5
= 7u^3 + 8u^3 + 8u^2 - 6u + 5 + 8
*Now add the like terms
= 15u^3 + 8u^2 - 6u + 13
And that is all your can do!
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
<h2>
</h2>
where
(x1 , y1) and (x2 , y2) are the points
Hope this helps you
Answer:
To find the slope of two given points, you can use the point-slope formula of (y2 - y1) / (x2 - x1). With the points plugged in, the formula looks like (3 - 2) / (4 - 1). Simplify the formula to get a slope of ⅓.

Answer:
12 inches = 1 foot
9,944 inches = 9,944/12 = 826.67 ft
Answer:
141.78 m
Step-by-step explanation:
Let d = distance of boat from the base of the lighthouse
Tan 10 = 25/d
d tan 10 = 25
d = 25/tan 10
d = 141.78 m
