use prime factors to find hcf of 18 12 56
Answers
Answer:
2 to the power of six times 3 cubed times seven.
Step-by-step explanation:
The prime factors of 56 are 2 cubed times 7 and the prime factors of 18 are 2 times 3 squared The prime factors of 12 are 2 squared times 3.
A factor is a number that divides another number, leaving no remainder
The highest common factor of 18, 12, and 56 using prime factors is 2.
What is a factor?A factor is a number that divides another number, leaving no remainder
Example: 12 = 4 x 3 where 4 and 3 are the factors of 12.
We have,
18, 12, and 56
The factors of each number are:
18 = 2 x 9, 3 x 6, 18 x 1
So the factors of 18 are 2, 3, 6, 9, and 18.
12 = 2 x 6, 3 x 4, 12 x 1
So the factors of 12 are 2, 3, 4, 6, and 12.
56 = 2 x 28, 4 x 14, 7 x 8, 14 x 4
So the factors of 56 are 2, 4, 7, 8, 14, and 28.
Thus,
The highest common factor of 18, 12, and 56 using prime factors is 2.

Answers
Answer:
117
Step-by-step explanation:
9^2 + 6^2 = 81 + 36
= 117
Answer: 117
Step-by-step explanation: To find the sum of 9² and 6², first you’ll have to find the whole number value of both integers (9² and 6²). Next, in order to do this, multiply 9 x 9 and 6 x 6. (9 x 9 = 81; 6 x 6 = 36). Lastly, add your two sums, being 81 and 36 to give you a final answer or sum of 117.

Your Turn Given the slope 8 and y-intercept 2 write the
equation of the line.
y =
Answers
Answer:
y = 8x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 8 and c = 2 , thus
y = 8x + 2 ← equation of line
The number for slope always has a x following it and the y intercept is 2 and because its a positive 2 , you add the 2.

15x + 5y = 20 y = 8 - 3x
Answers
Answer:
Step-by-step explanation:
15x+5y=8-3x
18x+5y=8⇒eqn 1
15x+5y=20y
15x-15y=0⇒eqn 2
eqn 1 * 3
54x + 15y=24⇒eqn 3
eqn 3 + eqn 2
69x=24
x=24/69=0.3478
eqn 1⇒
5y=8-18(24/69)
y=1.7391/5
y=0.3478
The solution to the system of equations is (10/3, -2).
What is an equation?Two or more expressions with an equal sign are defined as an equation.
The given equations are 15x + 5y = 20 and y = 8-3x.
15x + 15y = 20
Substitute y = 8-3x into the above equation:
15x + 15(8-3x) = 20
15x + 120 - 45x = 20
45x - 15x = 120 - 20
30x = 100
x = 10/3
Substitute x = 10/3 in y = 8 - 3x:
y = 8 - 3 (10/3)
y = 8 - 10
y = -2
Hence, the solution to the system of equations is (10/3, -2).

3/a + 2 − 6a/a2 − 4 = 1/a − 2
Answers
Answer:
No, the student did not check the solution to the derived equation in the original equation.
No, a possible solution is a = –2, but it does not check in the original equation because it makes two of the denominators equal to zero.
No, a = –2 is an extraneous solution, and there is no solution to the original rational equation.

3/a + 2 − 6a/2a − 4 = 1/a − 2 is - 2, the correct answer is 2/3.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, 3/a + 2 − 6a/2a − 4 = 1/a − 2.
3/a + 2 - 3 - 4 = 1/a - 2.
3/a - 1/a = 3.
2/a = 3.
a/2 = 1/3.
a = 2/3.
