Find the value of x - this is circle segments.
Given:
Diagram of a circle and its two secant from an exterior point.
To find:
The value of x.
Solution:
We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.
Using the above property, we get
[tex](x+7)x=(2+2)2[/tex]
[tex]x^2+7x=(4)2[/tex]
[tex]x^2+7x=8[/tex]
[tex]x^2+7x-8=0[/tex]
Splitting the middle term, we get
[tex]x^2+8x-x-8=0[/tex]
[tex]x(x+8)-1(x+8)=0[/tex]
[tex](x+8)(x-1)=0[/tex]
Using zero product property, we get
[tex](x+8)=0[/tex] and [tex](x-1)=0[/tex]
[tex]x=-8[/tex] and [tex]x=1[/tex]
Side cannot be negative.
Therefore, the only possible value of x is 1.

The surface area of a cube is 96 square inches. What is the length of an edge of the cube, in inches?
plz help, 7th grade math
Answer:
16 inches
Step-by-step explanation:
A cube has 6 sides and to find the surface area you would multiply one side by 6, or add the six sides together. So instead, to find the length of one side, you divide the surface area, 96, by 6 to get 16.
Hope this helps you :)
Answer:
Step-by-step explanation:
let x be the length of cube=x in
surface area=6 x²
6 x²=96
x²=96/6=16
x=√16=4 in

You now know a lot about all the angles formed from two straight lines that intersect. You know which angles are congruent and which angles are supplementary. Based on this information, you can find the angle measurements of all the angles even when you only know the measurement of one angle. In the figure below, angle 2 measures 145 degrees. What are the measurements of angles 1, 3 and 4? A angle 1 = 35 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees B angle 1 = 30 degrees, angle 3 = 30 degrees, angle 4 = 160 degrees C angle 1 = 35 degrees, angle 3 = 35 degrees, angle 4 = 145 degrees D angle 1 = 135 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees
Answer:
This is the correct way to set up the equation:
9x + 88 + 6x + 182 = 180
I'm going to move some things around so we can combine like terms. It now reads:
9x + 6x + 88 + 182 = 180
9x + 6x = 15x, so the equation now reads:
15x + 88 + 182 = 180
88 + 182 = 270, so the equation reads:
15x + 270 = 180
Subtract the 270 from both sides. 180 - 270 is -90:
15x = -90
Divide both sides by 15. -90 divided by 15 = -6:
x = -6
Now we can substitute -6 back into the separate equations.
9(-6) + 88 = ?
9 times -6 is -54. -54 + 88 = 34.
6(-6) + 182 = ?
6 times -6 = -36. -36 + 182 = 146
Now we can add 34 and 146 together.
34 + 146 = 180

You roll a die and flip a coin. What is the probability of NOT rolling a 4 on the die and flipping a heads on the coin?
Answer:
The probability of not rolling a 4 on the die and flipping heads on the coin is 5/6.
Step-by-step explanation:
Assuming the die is 6-sided, the probability of not rolling a 4 is 5/6, because all other possible values other than 4 can be rolled to make the probability true. 5/6
The probability of flipping heads on the coin is 1/2, considering there are 2 sides on the coin, heads, and tails.
To find the probability of both these events occurring, multiply both the probabilities together. (5/6) * (1/2) = 5/12.
