Answer: The answer is 12 cm and 32 cm.
Step-by-step explanation: Let, 'x' cm be the breadth of the rectangle, then according to the question, the length will be (x + 20) cm.
Also, given that if the smaller side is made two times larger and the larger side three times larger, then the perimeter of the new rectangle would be 240 cm. So, we have
So, the width of the original rectangle is 12 cm and its length will be (12 + 20) cm = 32 cm.
Thus, the lengths of the sides of original rectangle are 12 cm and 32 cm.
The first equation ;-)
It simplifies down to 3 = -5 which isn't true so, no solutions!
4(10n² - 2) - 5(8n² + 7) =
= 40n² - 8 - 40n² - 35 =
= 40n² - 40n² - 8 - 35 = -43 ← the end
Answer:
The answer is 1st point, 1/2×22.0×23.1
Step-by-step explanation:
You can let XY be the base and XZ be the height of the triangle. Then, by using the formula of the area of triangle, A=1/2×base×height to find the expression.

Answer: 6</h3>
Mark the locations -6 and 0 on the number line. Note that going from -6 to 0, or vice versa, will take exactly 6 steps. Put another way, the distance between 0 and -6 is 6 units. Absolute value represents distance, so it is never negative.
We say
Effectively, all we're doing is removing the negative sign.
