Answer 1

Answer:

x=10

Step-by-step explanation:

6^2+8^2=x^2

36+64=x^2

100=x^2

x=10

Answer 2

Answer:

Step-by-step explanation:

The pythagorean theorem states that a^2+b^2=c^2. a and b are the shorter sides and c is the hypotenuse, or the longest side. You can tell the hypotenuse because it is opposite to the right angle.

Therefore, a=6, b=8 and c=x. You can switch a and b if you like, it doesn't really matter.

using the pythagorean thm. 6^2+8^2=x^2. You simplify the exponents and combine like terms to get x^2=100. You take the square root of both sides and get 10.

Answer: 38

Step-by-step explanation:

Answer:

Perimeter= 38, EC- Area= 19.5

Step-by-step explanation:

substitute all the x's for 5. simplify each equation. H=3, Base= 13, 4x+2=22

h- 5-2=3

4(5)+2=22

base- 2(5)=3=13

then add all answers together to get 38.

multiply 13 and 3 to get 39, then divide by 2 to get 19.5 for the area.

Evaluate the expression. If necessary, round to the nearest hundredth.

1). what is the area of the rectangle whose length is (x+5) and width (x-5)?

Answers

Answer:

[tex]x^{2}[/tex]-25

Step-by-step explanation:

formula for areas of rectangles= width x height

width=x-5

height=x+5

(x-5)(x+5)= [tex]x^{2}[/tex]-5x+5x-25

since the 5x's cancel out each other

=[tex]x^{2}[/tex]-25 will be the answer

The area of rectangle is [tex](x^{2} -25)[/tex] unit square.

The area of rectangle is product of length and width.

[tex]Area = length*width[/tex]

Given that length is [tex](x+5)[/tex] and width is [tex](x-5)[/tex].

[tex]Area=(x+5)*(x-5)\\\\Area=x^{2} -5x+5x-25=x^{2} -25[/tex]

Hence, the area of rectangle is [tex](x^{2} -25)[/tex] unit square.

What would you multiply to make the y variable cross out?

-5x + y = -3

3x - 8y = 24

Answers

Answer:

Step-by-step explanation:

-40x + 8y = -24

3x - 8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24 (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3
