I'm assuming you're asking about negative or positive signs here. When I factor binomials, it depends on what would make factoring simpler for me. And how you're factoring the binomial too.
More often than not, it's going to be positive. For example, 4x^2 - 2x = 0. That would factor out to be 2x(2x-1) = 0. The sign outside is going to be positive because it's simpler to solve that way. Here, x is equal to 0 and equal to 1/2. Taking out a negative in this case would complicate the solving process.
Answer:
The area of cylinder 949.536 in²
Step-by-step explanation:
Points to remember
Curved surface area of cylinder = 2πrh
Where r - radius of cylinder
h - Height of cylinder
<u>To find the area of cylinder</u>
Here r = diameter/2 = 6.3/2 = 3.15 in
h = 48 in
Area = 2πrh
= 2 * 3.14 * 3.15 * 48
= 949.536 in²
Therefore area of cylinder 949.536 in²
Answer:
a= -20
Step-by-step explanation:
Answer:
A=174
Step-by-step explanation:
Step 1: Separate the figure into two separate shapes, a triangle and a square
Step 2: Find the dimensions of the triangle and square.
Square - l=12 w=12
Triangle - h=5, b=12. (The height was found by subtracting the length of the square (12) from the total length (17).
Step 3: Solve by using formulas
A=(5)(12)/2=30
A=12*12=144
Step 4: Add the parts together
144+30=174
A=174
Answer:
51.0791%
Step-by-step explanation:
Calculate percentage change
from V1 = 41700 to V2 = 63000
(V2−V1)|V1|×100
=(63000−41700)|41700|×100
=2130041700×100
=0.510791×100
=51.0791%change
=51.0791%increase
