Answer:
Step-by-step explanation:
- V(x) = x³ - 8x² + 19x - 12
<u>The two of the dimensions given</u>
<u>and the third one is</u>
<u>Multiply the three dimensions to get the volume:</u>
- (x - 1)(x - 3)(x + a) =
- (x² - 4x + 3)(x + a) =
- x³ - 4x² + 3x + ax² - 4ax + 3a =
- x³ - (4 - a)x² + (3 - 4a)x + 3a
Comparing with the given function, we get a = - 4
<u>So the missing dimension is:</u>
Answer:
50.24
Step-by-step explanation:
Area = r^2 x 3.14 (pi)
Radius = 8 ÷ 2 = 4
4² = 16
16 x 3.14 = 50.24
Area = 50.24 cm ²
It’s the second one, cuz that’s the correct formula and equation
Answer:
x+y=2
Step-by-step explanation:
Standard Form: ax+by=c
For most convenience start with slope-intercept form: y=mx+b
1. -1 = -1(3)+b - solve for b
b=2
y= -1x+2 (slope-intercept form)
2. Now convert to standard form
Add 1x to both sides:
1x+y=2
