Answer:
<h2>
<em><u>16h2</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>4h</u></em><em><u> </u></em><em><u>-</u></em><em><u> </u></em><em><u>42</u></em></h2>
Step-by-step explanation:
(4h + 6)(4h − 7)
= 4h(4h - 7) + 6(4h-7)
= 16h2 - 28h + 24h - 42
= <em><u>16h2 - 4h - 42 (Ans)</u></em>
Answer: 111.72 m^2 if they want round its 112
Is from O to C 14m
A=pixr^2
3.14x14^2= 615.44 m/2 half circle = 307.72
Area of triangle A= 1/2bh. .5x28x14=196
307.72-98=196= 111.72 m^2
Step-by-step explanation:
The slopes of two parallel lines must be identical.
We have slope

, so the slope for the parallel line be the same.
Now, to find an equation that also passes through the given point, we use slope-point form,

, where our point

is substituted for

.

Now, we convert to slope-intercept form as such.

And we are done. :) We can verify graphically that these are indeed parallel lines. See attached.
You forgot to add in your height to your question. To find your area you need to do 8 + 14 and get 22 then you nee to do the height divided by two. If you give me the height of the triangle I can tell you the area.
