Answer:
<h2>294mm²</h2>
Step-by-step explanation:
Surface Area = Sum of Area of all shapes.
There are 6 cubes which have a length of 7mm.
Area = L * L
Area = 7 * 7
Area = 49mm²
Surface Area = Area of 1 square * Number of Squares
Surface Area = 49 * 6
Surface Area = 294mm²

ANSWER: 74
The formula for the quadratic formula is x (c in this case) = (-b(+/-)√(b²-4ac))/2a
This is used for an equation in standard quadratic form: ax² + bx + c = 0
1.) Put it in the correct form, if not already in it.
Ex. c² + 6c + 8 = 0
2.) Identify each part of the equation:
a = 1 (the leading coefficient), b = 6 (the coefficient in front of the second variable), c = 8
3.) Plug in each variable answer
c = (-6(+/-)√(6²-4(1)(8))/2(1)
4.) Simplify
c = (-6(+/-)√(36-(4*8))/2
c = (-6(+/-)√(36-32))/2
c = (-6(+/-)√(4))/2
c = (-6(+/-)2)/2
*Here, the equation splits in two. It becomes:
c = (-6+2)/2 AND c = (-6-2)/2
*Simplify again:
c = -4/2 AND c = -8/2
c = -2 AND c = -4
The answers c = -2 and c = -4 would solve the given equation.
Hope this helps! :)
Answer:82
Step-by-step explanation:
surface area=pxh + 2xb
p=perimeter of base
h=height
b=area of base
Perimeter of base=7+7+2+2=18
height=3
base area=7x2=14
surface area=18x3+2x14
Surface area=82
