Please give a step-by-step solution of 2x^2 +12x = 6 (by completing the square)
Answer:
x = - 3 ± 2[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Given
2x² + 12x = 6 ( divide through by 2 )
x² + 6x = 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(3)x + 9 = 3 + 9
(x + 3)² = 12 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{12}[/tex] = ± 2[tex]\sqrt{3}[/tex] ( subtract 3 from both sides )
x = - 3 ± 2[tex]\sqrt{3}[/tex] ← exact solutions

When the fraction 1/4 is multiplied by a number less than 1 which of the following is always true?
The product is greater than 1.
The product is equal to 1.
The product is less than 1/4.
The product is greater than 1/4.
The option which is true is (c) The product is less than 1/4.
What are Fractions?Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.
Here p, called the numerator and q, called the denominator, are real numbers.
Given fraction is 1/4.
When 1/4 is multiplied by 1/2,
1/4 × 1/2 = 1/8 which is less than 1.
If 1/4 is multiplied by 3/4,
1/4 × 3/4 = 3/16, which is less than 8.
The least number that 1/4 is multiplied to gives the number 1/4 itself when multiplied by 1.
So, any number less than 1 when multiplied to 1/4 gives the number less than 1/4.
Hence the correct option is (c).

Myra owns a car service that charges a $5 flat rate and an additional $0.50 per mile.
Write an equation that represents this information.
Answer: 5 + 0.5m
Step-by-step explanation:
Let the number of miles be represented by m.
Therefore, since there's a $5 flat rate and an additional $0.50 per mile, this can be formed into a equation as:
= 5 + 0.5m
For example if the number of miles taken is 100miles, the amount charged will be:
= 5 + 0.5m
= 5 + 0.5(100)
= 5 + 50
= $55

What is the base area of a square pyramid of volume 216 cm3 and height 8 cm?
Answer:
We have the formula for pyramid volume V = (B.h)/3 => B = 3V / h
=> B = (216 . 3)/8 = 81 m2
the base area of a square pyramid : 81 m2
Step-by-step explanation:
Answer:
81cm2
Step-by-step explanation:
Volume = 1/3Base area * height
216 =1/3x * 8
3/8*216 =8/3x *3/8
x=81cm2
What is the measurement of this angle?
Answer:
140°
Step-by-step explanation:
The tool that the image is showing is a protractor. A protractor helps measure angles.To find the value of the angle you're measuring, look at the small numbers going around the protractor.The measure of the angle will be the number that shows under the other line. Since there are 2 numbers, remember this:If the flat line is on the left, use the number on top. If the flat line is on the right, use the bottom.Since this angle's flat part is on the left, use the top number for the measure. The measure is 140°.Point A(12, 0) is on the x-axis and point B(0,−5) is on the y-axis. Find the distance between points A and B
The table below shows a portion of the planned budget

Step-by-step explanation:
Given a number, a
Square of number = a²

Hence, Grogg is correct
I need help with number 9
Answer:
Square; x=2; y=1
Step-by-step explanation:
Being that the following quaderlateral has equal sides and angles equal to 90 degrees each, it would be classified as a square.
Now, knowing that they have all equal sides, you could say that
1). 5x-4=3x
as well as
2).2y+4=5y+1
Now, solve for each of the variables:
1). 5x-4=3x
(Minus 3x from both sides and add 4 to both sides)
2x=4
(Divide by 2)
x=2
2). 2y+4=5y+1
(Minus 5y from both sides and minus 4 to both sides)
-3y=-3
(Divide by -3)
y=1

solve the system of equations -3x+2y=-3 and -x-y=-11 by combining the equations
Answer:
x = 5
y = 6
Step-by-step explanation:
-3x + 2y = -3
-x - y = -11 (Multiply everything by 2)
-3x + 2y = -3
-2x - 2y = -22
-5x = -25
x = 5
-x - y = -11
-5 - y = -11
-y = -11 + 5
-y = -6
y = 6
