When scott woke up this morning, the temperature was 2°f. the temperature fell 5° by noon. scott used this number line to model the temperature drop. what error did scott make? a. scott should have started by moving from 0 to –5. b. scott should have started by moving from 0 to –2. c. scott started correctly by moving from 0 to 2, but then he should have moved 5 units to the left. d. scott started correctly by moving from 0 to 2, but then he should have moved 5 units to the right.

Step-by-step explanation: It's C

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

one peck is 9.309 quarts

9.309x 2
