So you need to turn 5x^2 -3x -9 into 2x - 3.
Well first you need to take 5x^2 out by subtracting 5x^2 (-5x^2).
Then -3x needs to become 2x by adding 5x (+5x).
Finally -9 needs to become -3 by adding 6 (+6).
Put all the things you did together to make a polynomial.
-5x^2 + 5x + 6
Answer:
each side of the hexagon measures 40 cm (which agrees with answer B)
Step-by-step explanation:
Recall that a regular hexagon has six equal sides, therefore, each side would be one sixth of the 240 cm:
each side of the hexagon = 240 cm / 6 = 40 cm
There are 514 gram rice in each container.
Step-by-step explanation:
Given,
Amount of rice = 6 kg
1 kg = 1000 g
6 kg = 6*1000 = 6000 g
Number of containers = 10
Rice left = 860 g
Let,
x be the amount in each container.
Total amount of rice - Number of containers*Amount in each container = Amount of rice left

Dividing both sides by 10

There are 514 gram rice in each container.

Answer:
A. 806.5 in²
Step-by-step explanation:
The figure given is a combination of a rectangle, a trapezoid and a triangle.
The formulas for the areas of each figure:
Rectangle: length x width
Trapezoid:
, where
and
are the lengths of each base and h is the height of the figure
Triangle: 1/2 bh, b = base and h = height
For each of the figures given:
rectangle: 16 x 9 = 144 in²
trapezoid:
= 352.5 in²
triangle: 1/2(31*20) = 310 in²
310 + 144 + 352.5 = 806.5 in²
