6u²*(2u-5)²-12u²*(2u-5)*(u+5)
-90u²*(2u-5)
Answer:
148, 32, 32
148, 148, 323
32, 148
Step-by-step explanation:
m<1 = m<4 = m<5 = m< 8 = 180 - 32 = 148 degrees
m<2= m<3 = m<6 = m<7 = 32 degrees
7x+18 = 2x+28
5x = 10
x=2
2*2 +28 = 32

DO IT ON YOUR OWN
Step-by-step explanation:
KIDDING UM CAN WE BE FRIENDS
AND TRUE
First you need to find the area of the plate.
The formula for the area of a circle is Area = pi *r^2
The radius (r) is given as 6 inches.
We will use 3.14 for pi
Area = 3.14 x 6^2
Area = 3.14 x 36
Area = 113.04 square inches.
Now to find the density, divide the total bacteria by the area:
Density = 120,000 / 113.04 = 1061.57 which rounds up to 1,062 bacteria/ square inch.
