1 answer:
agasfer [191]4 years ago
5 0

Answer:

D

Step-by-step explanation:

Use the distributive property.

8x3 + 20x2 + 20x for 4x's distribution.

-6x2 - 15x - 15 for -3's distribution.

Add these together, and add/subtract like terms. You're left with 8x3 + 14x2 + 5x - 15.

Given f(x) = 3x^2 + 2x – 1 and g(x) = 4x-5 find ( g of f) (-2)
pishuonlain [190]

Answer:

23

Step-by-step explanation:

Evaluate f(- 2) then substitute the value obtained into g(x)

f(- 2) = 3(- 2)² + 2(- 2) - 1 = 3(4) - 4 - 1 = 12 - 5 = 7 , then

g(7) = 4(7) - 5 = 28 - 5 = 23

In line 69, "perplex" most nearly means
lana [24]

The correct answer is option a) trouble

In line 69, "perplex" most nearly means trouble.

Despite the fact that the word "perplex" normally meant to leave someone feeling entirely perplexed, in this passage it suggests "trouble": Until there was nothing left to bother you, Mrs. Deverell, Angel had assumed all of the tasks.

Farmers assumed that these plates or the colony collapse disorder they were showing may be the source of this. Farmers believed that these common reasons were to blame.

There is the chance. These typical promises mites are said to be promises by farmers. Farmers believe that the chaos of colony collapse was caused by these shared goals.

That makes no sense since, as you may recall, we're talking about illnesses like fungus and might. The disturbed farmers also believe that colony collapse disorder is caused by these everyday problems. In any case, bacteria, fungi, and mites.
