Answer:
x = ±2sqrt(2)
Step-by-step explanation:
x^2 = 8
Take the square root of each side
sqrt(x^2) = ±sqrt(8)
x = ±sqrt(4*2)
We know that sqrt(ab) = sqrt(a)sqrt(b)
x = ±sqrt(4)sqrt(2)
x = ±2sqrt(2)
Lateral area = surface area <em>not including</em> the bases.
To find this area we just need to add up the area of all of those sides.
The 2 bases are the same area and defined by the length and width.
That leaves the 2 sides defined by length and height,
plus the 2 defined by width and height.
Of course, to find the area of a rectangle, we just multiply together its two dimensions.
length × height = 14 × 6 = 84
width × height = 9 × 6 = 54
2 × 84 + 2 × 54 = 276 m²
This is a multiplication problem, so you multiply 4 x 5 1/5. First change 5 1/5 into an improper fraction. Do this by multiplying the denominator and whole, then add the numerator. 5 x 5 + 1= 26. Improper fraction is 26/5. Now multiply 4 x 26/5. 4 x 26= 104. So it is 104/5. Now if you want a mixed number your answer is 20 4/5
1. $58.50
2. $72.80
3.no because 75 x .3 =22.50 and 22.50 + 75= $97.50
I think the answer is A. 49 units
