Answer:
The volume of the triangular prism is 
Step-by-step explanation:
we know that
The volume of the triangular prism is equal to
where
B is the area of the triangular face
L is the length of the prism
step 1
Find the area of the triangular face
The area of a triangle is equal to
we have
substitute
step 2
Find the volume
we have
substitute in the formula of volume
I am assuming theres an addition sign between the 3 and 4.
So basically you want to multiply the 5x by both terms so it will end up being
(5x•3) + (5x•4)
Now simplify:
15x+20x
Hope this helped ^_^
The formula for perimeter is 2L + 2W and the formula for the area is L * W, since we don't know the width we will divide 35:7 = 5 and he the measurement for the width.
Now just add L + W = 12 and multiply by 2 the answer is 24
Or 2 * 7 + 2 * 5 = 24

Step-by-step explanation:
Cheapstore:
500p÷10=50p×2=100p or £1
£4=600g
Superstore:

£5=780g
600÷4=150g per pound
