The low temperature on Monday was 16°F. On Tuesday, the low was 18°F cooler. On Wednesday, the low temperature was –4 times Tues
drek231 [11]

Answer:

-4(16-18), [16 + (-18)](-4)

Step-by-step explanation:

Given: The low temperature on Monday was 16°F. The low temperature on Tuesday was 18°F cooler. The low temperature on Wednesday was –4 times Tuesday’s temperature.

To find: expression that can be used to describe the low temperature on Wednesday

Solution:

Temperature on Monday = 16°F

So,

Temperature on Tuesday = (16-18)\°F

Temperature on Wednesday = -4(16-18)\°F

So, expression -4(16-18)=(16-18)(-4) can be used to describe the low temperature on Wednesday.

Also,

(16-18)(-4)=[16 + (-18)](-4)\,\,\left \{\because  (a-b)=\left [ a+(-b) \right ] \right \}

So, expression [16 + (-18)](-4) also represent temperature on Wednesday.

What is the sum of the polynomials?
Nadya [2.5K]

For this case we have the following polynomials:

-x ^ 2 + 9\\-3x ^ 2 - 11x + 4

Adding the polynomials we have:

(-x ^ 2 + 9) + (-3x ^ 2 - 11x + 4)

Rewriting we have:

x ^ 2 (-1-3) - 11x + (9 + 4)

Therefore, the result of the sum is:

-4x ^ 2 - 11x + 13

Answer:

the sum of the polynomials is:

-4x ^ 2 - 11x + 13

option 2
