Answer:
C.
Step-by-step explanation:
Hi there!
To answer this, we must set it up as
Now we just use the distributive property to solve.
this becomes 
I hope this helps!
Answer:
Step-by-step explanation:
If you treat (x+5) as a single value and (x-2) as the values of x and +2, you can distribute (x+5) to x and +2: ( (x-5)*x + (x-5)*2 ). Then you can treat x-5 as the values of x and -5 and distribute those to the numbers next to them: (×^2 - 5x) + (2x - 10). This results in x^2 -3x - 10.
Answer:
f = -25
Step-by-step explanation:
First add -32 to both sides, creating, 15 = -3/5f. Then you need to multiply both sides by the reciprocal of -3/5, which is -5/3. Giving you -25 as your answer.
with a scale factor
length becomes scale factor * length
area becomes scale factor^2 * area
volume becomes scale factor ^3 * volume
if the diameter is doubled the scale factor is 2
Volume becomes 2^3 * volume
the volume increases by a factor of 8
Answer:
16.5 ≈ x
Step-by-step explanation:
We have a right triangle where we know 1 side, 1 angle and we need to find another side. We can use trigonometric functions to find the missing side.
The tangent function definition is
tan α = opposite side/ adjacent side
In our problem
tan 70° = x/ 6, multiply both sides by 6 to isolate x
6 · tan 70° = x, use the calculator (make sure is set in degrees)
16.4848 ≈ x , round to the nearest tenths
16.5 ≈ x
