Answer:
15x^2-32x+9
Step-by-step explanation:
(3x – 1)(5x – 9)
FOIL
first: 3x*5x= 15x^2
outer: 3x(-9) = -27x
inner: -1(5x) = -5x
last: -1(-9) = 9
Add them together
15x^2 -27x-5x +9
Combine terms
15x^2-32x+9
Answer:
5 degrees
Step-by-step explanation:
We are given that during a science experiment
The temperature of a solution in a beaker 15 degrees below zero
The temperature of solution in a beaker 2 was opposite of the temperature in beaker 1
We have to determine the temperature of beaker 2.
It mean temperature of beaker 1 solution=-5 degrees
According to question
Temperature of beaker 2 solution =5 degrees
Hence, the temperature of solution in a beaker 2=5 degrees
120/4 = 30
120 x 2 = 240
240 + 30 = 270
270 grams of flour were used
Total paintings = 6
Number of different places for each painting = 6
Total number of ways she could hang all the painting = 6 × 6 = 36
The answer would be 2 hope this helps
