Answer:
A = 173.82
Step-by-step explanation:
[tex]A = 2 (1 + \sqrt{2}) a^{2}[/tex]
a = 6
substitute 6 for a
A = 2 (1 + [tex]\sqrt{2}[/tex]) [tex]6^{2}[/tex]
solve:
A = 2 (1 + [tex]\sqrt{2}[/tex]) 36
A = 173.82
Answer:
Around 173.8 km (rounded to the nearest tenth of a km
Step-by-step explanation:
The area of an octagon can be found using the expression:
A=2(1+sqrt of 2)a^2
plug your side of 6 in to create the following equation:
A=2(1+sqrt of 2)(6^2)
Solve for A:
A= (2 + 2*sqrt of 2)(36) I multiplied 6 by 6 to get 36 and used distributive property on the other section.
A=72+72sqrt of 2
plug that in a calculator and you get around 173.8 km

Answer: 4 squared + 2 squared is the least, 5 squared is in the middle, 6 squared - 6 is the greatest
Step-by-step explanation:
least in total=20
middle in total=25
greatest in total=30
Step-by-step explanation:
Here,
1st expression:
[tex] {6}^{2} - 6 = 36 - 6 = 30[/tex]
2nd expression:
[tex] {4}^{2} + {2}^{2} = 16 + 4 = 20[/tex]
3rd expression:
[tex] {5}^{2} = 25[/tex]
Hence, the order from least to greatest is,
20 < 25 < 30
Also,

A triangular pane of glass has a height of 42 inches and an area of 546 square inches. What is the length of the base of the pane?
Answers
Answer:
Base = 26 in
Step-by-step explanation:
Recall the formula for the area of a triangle as:
Area = (Base x Height) / 2
In our case, this formula converts into:
546 in^2 = Base x 42 in /2
multiply both sides by 2 to get rid of fractions:
1092 in^2 = Base x 42 in
divide both sides by "42 in" to isolate the Base completely
1092 in^2 / 42 in = Base
Therefore Base = 26 in

f(x)=(−2)^3 (3)^0 (4)^−2
(−2)^3 = -8
(3)^0 =1

Lupe and her friends spent $20 on snack mix and water. They bought x bags of snack mix and y bottles of water. They bought a total of 11 items. How many bags of snack mix did they buy?
Answers
Answer:
6 bags of snack mix
Step-by-step explanation:
x bags of snack mix
y bottles of water
The equations in the question is given as;
20.00 = 2.50x + 1.00y (i)
11 = x + y (ii)
From eqn (ii);
11 - y = x
substitute the value of x in eqn (i);
20.00 = 2.50(11 - y) + 1.00y
20.00 = 27.5 - 2.50y + 1.00y
20.00 - 27.5 = - 1.50 y
- 7.5 = - 1.50 y
y = - 7.5 / (- 1.5) = 5
Since we are interested in the value of x. Substitute the value of y in eqn (ii);
11 = x + 5
x = 11 - 5 = 6
