Answer:
A.26
B. 3.4
Step-by-step explanation:
A. Using the Pythagorean theorem, we get x^2= 24^2+10^2. Solving for x, we get x=26.
B. Using the Pythagorean theorem again, we get x^2=3^2+1.6^2 solving for x, we get x=3.4

Step-by-step explanation:
Answer:
meters
Step-by-step explanation:
The bathroom is in the shape of a square. The area of square is given as:
Where
s is the length of the side
We know area is 100, thus:
The side length of the square is 10 meters.
The distance from one corner to another corner is known as the "diagonal".
We use the formula below to get the distance of the diagonal:
Where
d is the length of diagonal
s is the length of side [here, 10]
THus, length of diagonal is:
meters
The answer is the last option (Option D), which is:
D. 25
The explanation is shown below:
1. You have that:
(a ± b)^2=a^2 <span>± 2ab + b^2
2. The expression given in the problem is:
</span><span>x^2-10x+n
Where x^2=a and 2ab=10x
2b=10
b=10/2
b=5
3. Therefore, you have:
b^2=5
b^2=25
b^2=n
n=25</span>
Answer:
The length is 14 m.
Step-by-step explanation:
length = L
width = W
perimeter = P
"The perimeter of a rectangle is twice the sum of its length and its width."
P = 2(L + W)
"The perimeter is 40 meters"
40 = 2(L + W)
"and its length is 2 meters more than twice its width."
L = 2W + 2
Replace L with 2W + 2 in equation 40 = 2(L + W):
40 = 2(2W + 2 + W)
40 = 2(3W + 2)
20 = 3W + 2
3W = 18
W = 6
The width is 6 meters.
L = 2W + 2 = 2(6 m) + 2 m = 12 m + 2 m = 14 m
Answer: The length is 14 m.
