find the missing side each triangle.round your answers to the nearest tenth if necessary
Answer:
x = 6
Step-by-step explanation:
The triangle is a right triangle, as denoted by the red square at the bottom, we can use the Pythagorean Theorem to figure out the second side (since we are given the other side and the hypotenuse).
a² + b² = c²
(8)² + b² = (10)²
64 + b² = 100
b² = 100 - 64 = 36
b = ±[tex]\sqrt{36}[/tex]
b = ± 6
But we know that distance is always positive, so
b = 6
I have used b in place of x if you are confused about the variable usage.

Go step by step to reduce the radical.
Answer:
Step-by-step explanation:
You can begin by breaking down √(160) into its prime factors.
160 = 2 * 2 * 2 * 2 * 2 * 5
√(160) = √(2 * 2 * 2 * 2 *2 * 5)
This can be broken down further by
2 * 2√2 * 5
For every 2 factors that are the same, take one outside the brackets
4 √10
I suppose the way you are supposed to write this is √16 * √10
I'm not sure I'm right. There are 2 square root signs there and it is the only way I can think of to use 2 square root signs.

Select the quadratic equation that has no real solutions. 25x-10x+4=0
Answer:
Step-by-step explanation:
Were there not several equations from which to choose?
The coefficients of 25x^2 - 10x + 4 are {25, -10, 4}. The discriminant is thus b^2 - 4ac, or (-10)^2 - 4(25)(4), or 100 - 400, or -300. Because the discriminant is negative, the quadratic has no real solutions.
The quadratic equation with no real solution is 25x²-10x+4 = 0
What is a quadratic equation?The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Given that, which of the equations have no real solution,
Considering the quadratic equation 25x²-10x+4 = 0
D = [tex]\sqrt{b^{2} -4ac}[/tex]
We know, when √D > 0, real roots
√D = 0, equal roots
√D < 0, imaginary roots
[tex]\sqrt{b^{2} -4ac}[/tex] =
[tex]\sqrt{10^{2} -400} \\\sqrt{-300}[/tex]
Since, the discriminant is less than 0, therefore, its roots are imaginary.
Hence, The quadratic equation with no real solution is 25x²-10x+4 = 0

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the exponents and indices.
here, we should remember one thing that,
3 ^3 = 27 and 1/3^x = 3^-x
so we get as,
(3^-3)^4-x = (3^3)^2x-1
==> 3^-12+3x = 3^6x-3
since the base is same that is 3 , we equate their powers.
-12x+3=6x-3
==> 3+3 = 6x+12x
==> 6 = 18x
hence ===> x = 6/18 = 1/3
hence, x = 1/3

enter the equation of the line in the form =mx where m is the slope .
Answer:
y = 3x
Step-by-step explanation:
The line goes up 3 and goes across by 1. Using the rise over run structure, it will be 3/1 or 3. m is equal to the slope, making it y = 3x, since y doesn't intercept anything, you don't need to put + anything at the end. Hope I helped. :D

Mike took a taxi from his home to the airport. The taxi driver charged an initial
fee of $6 plus $3 per mile. The total fare was $24, not including the tip. How many
miles did mike travel by taxi on this ride?
A. 2
B. 6
C. 8
D.10
Answer:
B. 6
Step-by-step explanation:
SInce the total amount paid by Mike was $24, you subtract the initial amount he paid ($6) which leaves you with $18. Since the taxi driver charges $3 per mile you divide $18 by $3 to get 6 so that means Mike travel 6 miles.

Question:
x + 3 < 5, Find x.
Answer
⟹ x + 3 < 5
( Subtracting 3 from both the sides of the inequality )
⟹ ( x + 3) - 3 < 5 - 3
⟹ x < 5 - 3
⟹ x < 2
It means that any number that is smaller than 2 will satisfy the inequality.
