Answer:
-22
Step-by-step explanation:
We need to multiply the following:
[tex](\sqrt{10} +2\sqrt{8})(\sqrt{10}-2\sqrt{8})[/tex]
First, we need to FOIL out this expression, then we can simplify it
[tex](\sqrt{10} +2\sqrt{8})(\sqrt{10}-2\sqrt{8})\\\\(\sqrt{10})( \sqrt{10} )+(2\sqrt{8})(\sqrt{10})-(2\sqrt{8})( \sqrt{10})-(2\sqrt{8})(2\sqrt{8}) \\\\10+2\sqrt{80} -2\sqrt{80} -4\sqrt{64} \\\\10-4(8)\\\\10-32\\\\-22[/tex]
The simplified expression after you multiply (square root 10 + 2 square root 8)( square root 10 - 2 square root 8) is -6.
What is simplified expression after you multiply?To solve the given expression that needs you to multiply, let's first simplify the individual terms:
Square root of 10: √10
Square root of 8: √8 = √(4 x 2) = 2√2
Now, let's substitute these values into the expression:
(√10 + 2√8)(√10 - 2√8)
Using the distributive property, we can expand this expression as follows:
= (√10 x √10) - (√10 x 2√8) + (2√8 x √10) - (2√8 x 2√8)
= 10 - 2√80 + 2√80 - 4 x 8
= 10 - 16
= -6
Therefore, the simplified expression in square root is -6.

A single candy is picked
randomly from a bag
containing 5 red, 4 Green, and
3 blue. Give the probability of
picking a candy that is not blue.
Answer:
9/12 or 3/4 (it's the same)
Step-by-step explanation:
You have to guve the probabiloty of picking a candy that is not blue, so you have to do:
5 red + 4 green = 9
total = 5 + 4 + 3 = 12
9/12 is equal to 3/4
Step-by-step explanation: the answer is3/12
it is 3/12 because if you add 5+4+3 you will get 12 so out of that 12 which are blue which is 3 so it would be three
if it is wrong sorry but if it right hope its was correct :)

Answer: The area of the banner is 100 in^2
Step-by-step explanation:
so let say the banner was still a rectangle with the triangle still attached to it so if we needed to find the area of the whole rectangle we will need to multiply the length times the width
so 14 * 8 = 112
But now a triangle is being cut out of the rectangle so we need to find the area of the triangle being cut out and subtract it from the area of the whole rectangle. But first we need to find the base and the base is 8 since the other side base is 8 too and the height will be 3 since 14- 11= 3
Now find the area of the triangle by multiplying the base times the height and divide it by 2.
8 * 3= 24
24/2= 12
subtract 12 from 112
112- 12 = 100
The volume of a cylinder is 576Pi cubic inches. The radius of the circular base is 4 inches. What is the height of the cylinder?
Recall the formula V = pi r squared h.
18 inches
24 inches
36 inches
72 inches
Answer:
The height of the cylinder is 36 inches
Step-by-step explanation:
Given, The volume of a cylinder is 576[tex]\pi[/tex] cubic inches and the radius is 4 inches.
[tex]\pi[/tex] = 3.14
Formula for voulme of cylinder is V = [tex]\pi[/tex] * r^2 * h
Substitute the given values in the above formula to find the unknown value.
V = 3.14 * 4^2 * h
576[tex]\pi[/tex] = 3.14 * 4^2 * h
1,808.64 = 3.14 * 16 * h
1,808.64 = 50.24 * h
1,808.64 / 50.24 = h
36 = h
h = 36 inches
The final answer is 36 inches.
Therefore the height of the cylinder is 36 inches.

If 1/10 < x < 1, for what value of x is the value of 10 + 1/x greatest?
Help quick pleaseee
Answer:
Step-by-step explanation:
We can safely focus on 1/x. The smaller x is, the greater 1/x will be. Note that x cannot equal zero. Here we are asked to focus on 1/10 < x < 1, in which 1/10 is obviously the smallest x value. But 1/10 < x < 1 restricts x to numbers greater than 1/10. The graph of y = 10 + 1/x is not defined for x = 1/10, but as we approach x = 1/10 along the graph, we see the graph approaching (but not touching) the maximum value 10 + 1/(1/10), or 20.

Let's solve your equation step-by-step.
5x+34+8x+15=88
Step 1: Simplify both sides of the equation.
5x+34+8x+15=88
(5x+8x)+(34+15)=88(Combine Like Terms)
13x+49=88
13x+49=88
Step 2: Subtract 49 from both sides.
13x+49−49=88−49
13x=39
Step 3: Divide both sides by 13.
