Answer:
This expression is not factorable with rational numbers.
Step-by-step explanation:
The way factoring works, you just want to get it to its smallest form possible. To do that you would divide the entire problem by the Least Common Multiple.
This problem does not have a least common multiple. The LCM of 16 and 64 is 16 but x^2 does not have a number in front. 16k and 64 can be factored but in order to factor the entire problem, x^2 would need to have a number in front that made it divisible by a common multiple of 16 and 64.
Say if the problem was 2x^2+16k+64, you could divide the entire problem by 2. Your answer would be:
2(x^2+8k+32)It is important to note that when you are factoring, never divide any exponents.
The way to check your work when factoring is to distribute the number outside of the parentheses. So in the example I just gave, you'd multiply everything in the parentheses, except the exponent, by 2. Which will give you the original 2x^2+16k+64.
Whatever number you factor out and end up putting outside your parentheses, should multiply back into the parentheses to give you the original problem. If it doesn't, then the factoring was done incorrectly.
Your answer should include parentheses.

Answer:
y = [tex]\sqrt{19^2 + 8.2^2}[/tex]
Step-by-step explanation:
to get the hypotenuse:
use the Pythagorean theorem:
a² + b² = c²
where a = 19, b = 8.2 c = y
plugin values:
19² + 8.2² = y²
y = [tex]\sqrt{19^2 + 8.2^2}[/tex]
Answer:
y = [tex]\sqrt{19^2+8.2^2}[/tex]
Step-by-step explanation:

Jenna found three solution to a linear equation she graphed them, but they don't lie in a straight line. What errors could jenna have made? Explain.
Answer:
A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.
A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.
There are many different methods in arriving to the final answer. However, errors cannot be perfectly avoided. One of these errors to mistakenly identify equations as linear. It is important that we know that the equations we are dealing with are of exact or correct characteristics.
Also, if she had used substitution method, she might have mistakenly taken the value of one variable for the other.
In the diagram shown below, Points M, N and P are collinear. If MN = 3x-9, NP = x+1 and MP= 6x-22, solve for the value of X (Answer notation: x=__)
Answer:
The value of x is 7
Step-by-step explanation:
M, N and P are collinear means they lie on the same line.
Mathematically;
MP = MN + NP
Thus;
6x-22 = 3x -9 + x + 1
6x-22 = 4x -8
6x -4x = -8 + 22
2x = 14
x = 14/2
x = 7
2/3 divided by 4/5 qwertyuioppasdfghjklzxcvbnm
Answer:
5/6
Step-by-step explanation:
The solution of the given fraction is 5/6.
Given that:
Fraction: divided 2/3 by 4/5
To calculate the division of fractions, simply need to multiply the first fraction by the reciprocal of the second fraction.
[tex]\dfrac{2/3}{4/5} =\dfrac{2}{3} \times \dfrac{5}{4}\\\dfrac{2/3}{4/5} =\dfrac{(2 \times5)}{(3 \times4) }\\\dfrac{2/3}{4/5} =10 / 12[/tex]
To simplify the fraction, you can divide both the numerator and the denominator by their greatest common divisor, which is 2:
10 / 12 = 5 / 6
So, 2/3 divided by 4/5 is equal to 5/6.
Hence, the required result is 5/6.

1. If the same 1.0 kg book is lifted 0.5 m above the table, but the table top is 1.0 m
above the floor, what would be the potential energy of the book if the reference level we
the floor?
Answer:
Potential Energy = 10J
Step-by-step explanation:
mass of the book = 1.0kg
height = (0.5 + 1)m
acceleration due to gravity = 10m/s²
Potential Energy = mass × acceleration × height
Potential Energy = 1kg × 10m/s² × 1m
Potential Energy = 10J
