X subtracted from y means y-x
(4x^2-4x+3)-(2x^2-6x-4)
4x^2-4x+3-2x^2+6x+4
4x^2-2x^2-4x+6x+3+4=
2x^2+2x+7
Answer:
Slope = 
4x + 3y = 23
Step-by-step explanation:
slope = 
The equation:
m is the slope
y - 5 = -4/3 (x - 2) Multiply both sides by 3
3y -15 = -4 (x - 2)
3y - 15 = -4x + 8
3y + 4x = 8 + 15
3y + 4x = 23
4x + 3y = 23
Answer:
The area is approximately 453 ft²
Step-by-step explanation:
Area of a circle = 
If 
= 22/7, and r = 12 ft
Area = (22/7)×12²
= 3.143*144
= 452.592 ft²
≈ 453 ft²
Answer: c
Step-by-step explanation:
You have to find the area of the base, step 2 multiply by the height. Then multiply length and radius in a circle of a base. The correct answer is C. use the diameter to find the radius of the cylinder to find the volume.
Answer:
360 degrees in total.
Step-by-step explanation:
We are given that the m∠1 is 145 degrees, and because ∠1 and ∠2 form a straight line we can tell that 180-145 = 35.
So now here's what we know:
m∠1 = 145
m∠2 = 35
After that, we need to look at ∠5 and ∠6.
One thing we can notice right away is that ∠5 and ∠6 should measure the same as ∠1 and ∠2 (respectively) because they are corresponding angles.
Now we will add them all together to find the sum of all four angles.
m∠1 = 145 + m∠2 = 35 = 180
m∠5= 145 + m∠6 = 35 = 180
180 + 180 = 360
