Answer:
A. 96
Step-by-step explanation:
The surface area is the sum of the areas of the two triangular bases and the areas of the three rectangular lateral faces.
A = 2(1/2)bh + PH
where b is the base of the triangle, h is its height, P is the perimeter of the triangle, and H is the height of the prism.
A = (3 cm)(4 cm) +(3 +4 +5 cm)(7 cm) = 12 cm² +84 cm²
A = 96 cm²
The surface area of the triangular prism is 96 square cm.
I hope you might have understood.

Answer:
each hamburger costs $3.50
Step-by-step explanation:
he spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equaton,
2.50 + 3h = 13 now solve for x
-2.50 2.50
3h = 10.50
h=3.50
check:
2.50+3(3.50)=13
2.50+10.50=13
13=13
"Standard form" is the form ...
... ax +by = c
where a, b, c are mutually prime integers and the leading coefficient is positive. (If a ≠ 0, then it is "leading". If a = 0, then b is the leading coefficient.)
Of the choices offered, the only one that is equivalent to the given equation is ...
... -x + 6y = 5
_____
However, "standard form" requires the leading coefficient be positive, so an appropriate answer would be ...
... x -6y = -5
or
... 6y -x = 5
____
This is another one for my "broken question" file.
