Answer:
x = 4
Step-by-step explanation:
x + 4(x+5) = 40 (Given)
x + 4x + 20 = 40 (Distribute the 4 into the x and 5)
5x + 20 = 40 (Add like terms)
5x = 20 (Subtract 20 on both sides)
x = 4 (Divide 5 on both sides)

Step-by-step explanation:
This would have no solution because when you try to solve the equation and simplify, the 4x's cancel out, leaving no variable and making the equation reduce to: -8=9 which is false, and therefore, this has no solution.

4÷16/17=
Answers
Step-by-step explanation:
Turn 4 into 4/1. Then switch 4/1 or 16/17 because I don't know which to switch. If you don't know what I'm talking about, when you switch 4/1 or 16/17, you'll get 1/4 or 17/16. Then you multiply 1/4 × 16/17 or 4/1 × 17/16. You multiply across, like this, 1 × 16 and 4× 17 Same thing with 4/1 × 17/16 but backwards (4×17 and 1×16). Do both equation (4/1 × 17/16 and 1/4 × 16/17) by yourself, then simplest it. Example: 2/4 = 1/2. You divide 2/4 by two, 2÷2 for the numerator and 4÷2 for the denominator. That how you simply.

1. A right angled triangle has two shorter sides and one is twice as long as the other. The hypotenuse is 25 cm long. What are the lengths of the shorter sides?
Answers
Step-by-step explanation:
The hypotenuse of a right-angled triangle = 25 cm
One side is twice as long as the other.
Let the other side is x.
First side = 2x
Using Pythagoras theorem to find the lengths of the shorter sides.
[tex]x^2+(2x)^2=25^2\\\\x^2+4x^2=625\\\\5x^2=625\\\\x^2=125\\\\x=11.18\ cm[/tex]
So, the other side = 11.18 cm
First side = 2(11.18) = 22.36 cm
So, the lengths of the shorter sides are 11.18 cm and 22.36 cm.

I’m really hoping I do fail this assignment so can someone please help?
Answers
the answer is 99!
here is an explanation to help you understand:
the angles 81 degrees and b are supplementary angles. Supplementary angles mean that two angles have the sum of 180 degrees so you would need to find the x when you have a given already.
do an equation like this:
x + 81 = 180
here is how to answer the equation:
x + 81 - 81 = 180 - 81
x = 99
Here you only need to subtract 81 from both sides. in simple terms, do 180 minus the measure given.

Given:
Two triangles are given in the figure.
To find:
The m∠K and m∠J.
Solution:
In triangle FHK and IGJ,
[tex]m\angle F=m\angle I[/tex] [Given]
[tex]m\angle H=m\angle G[/tex] [Given]
Two corresponding angles are equal. So,
[tex]\Delta FHK\sim \Delta IGJ[/tex] [By AA similarity theorem]
All corresponding angles of similar figures are same.
[tex]m\angle K=m\angle J[/tex] ...(i)
[tex]4y^2=6y^2-40[/tex]
[tex]4y^2-6y^2=-40[/tex]
[tex]-2y^2=-40[/tex]
Divide both sides by -2.
[tex]y^2=20[/tex] ...(ii)
Taking square root on both sides.
[tex]y=\pm \sqrt{20}[/tex]
Now,
[tex]m\angle K=(4y^2)^\circ[/tex]
[tex]m\angle K=[4(20)]^\circ[/tex] [Using (ii)]
[tex]m\angle K=80^\circ[/tex]
[tex]m\angle K=m\angle J=80^\circ[/tex] [Using (i)]
Therefore, the m∠K is 80° and m∠J is 80°.

The measure of the value of x is 11
Properties of a parallelogramOne of the properties of a parallelogram is that the diagonals of a parallelogram bisect each other.
Given the diagonals with the sides x + 4 and 2x-7, equating both expresions will give:
x + 4 = 2x - 7
x - 2x = -7 - 4
-x = -11
x = 11
Hene the measure of the value of x is 11

Find the range for the possible measure of the third side of a triangle given two sides?
4 cm, 6 cm
Range:
Answers
Answer:
The possible range of the measure of the third side is 2 < 3rd side < 10
Step-by-step explanation:
In any triangle:
The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sidesLet us solve the question
∵ The measures of the two sides of a triangle are 4 cm and 6 cm
∵ The difference between their measures = 6 - 4 = 2 cm
∵ The sum of their measures = 6 + 4 = 10 cm
→ By using the rules above
∴ The measure of the third side is between 2 and 10
∴ 2 < the third side < 10
∴ The possible range of the measure of the third side is 2 < 3rd side < 10
