Answer:
Box 1 = -4
Box 2 = -3
Box 3 = -5
Step-by-step explanation:
-4 + 2x - 5(1 + x)
=> -4 + 2x - 5 - 5x
=> -4 + (2x + - 5x) -5
=> -4 - 3x - 5
This equation can no more be divided / simplified, so,
The answer = -4 - 3x - 5
So, in the boxes, the answer will be,
Box 1 = -4
Box 2 = -3
Box 3 = -5

Answer:
BD = 35
Step-by-step explanation:
Calculate CD in right triangle ABC, then BD in right triangle BCD
Using Pythagoras' identity in both triangles.
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
In Δ ADC
CD² + AD² = AC² , substitute values
CD² + 9² = 15²
CD² + 81 = 225 ( subtract 81 from both sides )
CD = 144 ( take the square root of both sides )
CD = = 12
----------------------------------------------------------------
In Δ BCD
BD² + CD² = BC² , substitute values
BD² + 12² = 37²
BD² + 144 = 1369 ( subtract 144 from both sides )
BD² = 1225 ( take the square root of both sides )
BD = = 35
Answer & Step-by-step explanation:
When we see the phrase "rate of change" then it means that we are looking for the slope. So, we will need to know the formula for finding slope or the rate of change.
Now, let's use this equation to solve for the rate of change of each question.
<u>Problem 1:</u>
<em>The rate of change of this equation is 2/3</em>
