Answer:
5\sqrt{2} + \sqrt{10}
Step-by-step explanation:
I assume the exp as [tex]\sqrt{5} (\sqrt{10} + \sqrt{2} )[/tex]
[tex]\sqrt{50 } + \sqrt{10}[/tex]
[tex]\sqrt{25*2} +\sqrt{10}[/tex]
[tex]5\sqrt{2} + \sqrt{10}[/tex]
The simplified form of the given expression [tex]\sqrt{5} (\sqrt{10} +\sqrt{2} )[/tex] will be [tex]5\sqrt{2} + \sqrt{10}[/tex].
What is a perfect square?A perfect square is a number system that can be expressed as the
square of a given number from the same system.
The given expression is as follows;
[tex]\sqrt{5} (\sqrt{10} +\sqrt{2} )\\\\\sqrt{5} \times \sqrt{10} +\sqrt{5} \times\sqrt{2} \\\\\sqrt{25 \times 2} +\sqrt{10}\\\\5\sqrt{2} +\sqrt{10}[/tex]
Hence, the simplified form of the given expression is [tex]5\sqrt{2} + \sqrt{10}[/tex].

Use the ratio to find the measurement. (4 points: 1 point for the method, 2 points for shown work, 1 point for the answer)
6. Confirm that your answer to question 5 is correct using the Pythagorean Theorem instead of trig ratios. (3 points)
Answer:
The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.
Step-by-step explanation:
You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x
=> x = 50 m / tan(86°)
x = 50 m / 14.30 = 0.98 m

Step-by-step explanation:
Find the value of x, then the perimeter of the regular polygon.
I have attached the image that shows the ploygon.
Answer:
x = 3
perimeter: 18 units
Step-by-step explanation:
1. First, we should know that a regular polygon is a polygon that has all angles the same angle measure and all sides the same side length.
For example, an equilateral triangle is a regular polygon because all angles are 60 degrees and all sides are the same length.This means that for the polygon in the image, 5(x+2) = 7x + 42. (Solving)
Step 1: Simplify both sides of the equation.
[tex](5)(x)+(5)(2)=7x+4[/tex] [tex]5x + 10 = 7x + 4[/tex]Step 2: Subtract 7x from both sides.
[tex]5x + 10 - 7x = 7x + 4 - 7x[/tex] [tex]-2x + 10 = 4[/tex]Step 3: Subtract 10 from both sides.
[tex]-2x + 10 - 10 = 4 - 10[/tex] [tex]-2x = -6[/tex]Step 4: Divide both sides by -2.
[tex]\frac{-2x}{-2} = \frac{-6}{-2}[/tex] [tex]x = 3[/tex]Step 5: Check if solution is correct.
[tex]5(3+2)=7(3)+4[/tex] [tex]5(5)=21+4[/tex] [tex]25 = 25[/tex]3. Now, since this polygon has 6 sides, it's a hexagon. To find the perimeter of a hexagon, we just multiply the length of one side 6 times.
[tex]3(6)[/tex] [tex]18[/tex]Therefore, x = 3 and the perimeter is 18 units.

Find the slope of a line parallel to the line whose equation is y-4=7(x+2).
Answer:
m'=7
Step-by-step explanation:
they are parallel to each other so if slope of 1st line be "m" and 2nd line as "m' ", then we have:
m = m'
y-4=7x+14
y=7x+18
y=mx+h
So m = 7
& m' = 7

Answer:
x = -2
Step-by-step explanation:

-5 ≤x≤6
[-5,6]
Answer:
[-5, 6]
Step-by-step explanation:

It's equilateral. Equilateral triangles are three equal-sided polygons. Remember that. It helps.
Help me on this math question please
Answer:
Solution:-
Let the angle vertical to 64°be y.
y=64°(being vertically opposite angle)
Now,
X+y+62°=180°
X+64+62=180°
X=180°-126°
Therefore,x=54°
