The percentage of increase in area will be 300%
<em><u>Explanation</u></em>
By doubling each dimension, the area of a parallelogram increased from 36 square centimeters to 144 square centimeters.
So, the increased area = Final area - Initial area = (144 - 36)cm² = 108 cm²
Now, for finding the percentage of increase, first we need to <u>divide "the increased area" by the "initial area" and then multiply by 100% </u>
Thus, the percentage of increase in area

Answer:
C
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 )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line
m =
= ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
note that the line crosses the y-axis at (0, - 2) ⇒ c = - 2
y =
x - 2 ← equation of line
Answer:
You need to add: <span> <span>x2</span>+x+6</span>
Explanation:
Let the unknown part be represented by A
Then we have: <span> 3x−7+A=<span>x2</span>+4x−1</span>
Subtract <span>3x</span> from both sides
<span>−7+A=<span>x2</span>+4x−3x−1</span>
but <span>4x−3x</span> is giving:
<span>−7+A=<span>x2</span>+x−1</span>
Add 7 to both sides
<span>A=<span>x2</span>+x+6</span>
So you need to add: <span><span>x2</span>+x+<span>6</span></span>
List the hours from 1 to 8
Multiply the hours by how much she is paid per hour ( $12)
X: 1, 2, 3, 4, 5, 6, 7, 8
y: 12, 24, 36, 48, 60, 72, 84, 96
Answer:
c = 4
Step-by-step explanation:
p(x) is divisible by (x - 3).
So, p(3) = 0
-(3)³ + c(3)² - 4 *3 + 3 = 0
-27 + 9c - 12 + 3 = 0
9c - 36 = 0
9c = 36
c = 36/9
c = 4
