Answer:
5100 mm², hope that helps! (OwO)
Step-by-step explanation:
surface area]=2*[area of the base]+[perimeter of the base]*height
area of the base=30*70-----> 2100 mm²
perimeter of the base=2*(30+70)-----> 200 mm
height=4 1/2 mm-----> (4*2+1)/2-----> 9/2 mm
[surface area]=2*[2100]+[200]*9/2-----> 5100 mm²
The question is asking to calculate the value of c base on the restriction in the said problem and in my further research and further calculation, the answer are the following:
A. the value of C in unsimplified form is c is sqrt of 18
B. the value of C in simplified for would be 4.2426
C. the rounded value of c is 4.24
9(p - 4) = -18
Simplify our equation by multiplying the parenthesis out.
(9 × p) + (9 × -4) = -18
Simplify.
9p + (-36) = -18
Get rid of parenthesis.
9p - 36 = -18
Now, since we're trying to isolate "p," we need to add 36 to both sides.
9p - 36 + 36 = -18 + 36
Simplify.
9p = 18
Divide both sides by 9.
9p ÷ 9 = 18 ÷ 9
Simplify.
p = 2

Wouldn't it just be the same as angle B?
