Really need help, I’m trying to catch up in my math and get my marks back up before mid term..
Luba_88 [7]

Answer:

a) 12x + 22   b) 17x^{2} - x

Step-by-step explanation:

Perimeter is the sum of the each side length.

The first example is a rectangle so the (4x+8) and the (2x+3) are doubled.

(4x+8) x 2 = 8x+16

(2x+3) x 2 = 4x + 6

12x+22

(6x^{2} - 12x) + (2x^{2} + x) + (9x^{2} + 10x)

combine like-terms.

17x^{2} - x

P(x) = x^4+ax^3-x^2+bx-12 has factors of (x-2) and (x+1). Solve the equation P(x)=0​
Feliz [49]

Answer:

because P(x) has factors of (x-2) and (x+1) => x = 2 and x = -1 are the solutions of P(x)

so we have:

\left \{ {{2^{4}+2^{3}a-2^{2}+2b-12   =0} \atop {1-a-1-b-12=0}} \right.\\=>\left \{ {{8a+2b=0} \atop {a+b=-12}} \right.\\\left \{ {{4a+b=0} \atop {a+b=-12}} \right.\\\left \{ {{a=4} \atop {b=-16}} \right.

=> P(x)=x^{4} + 4x^{3}-x^{2} -16x-12

With P(x) = 0

=> x^{4}+4x^{3}-x^{2} -16x-12 = 0

=> ........

What is the answer to this question?
Vilka [71]

Answer: Choice A) 4, 3, 5, 1, 2

=====================================================

Explanation:

Since tan(x) = sin(x)/cos(x) is a known and widely used trig identity, this must mean step 4 goes first.

The answer is between choice A and choice B.

The question is now: What is the correct second step?

It's either step 3 (choice A) or step 5 (choice B)

It turns out that step 3 is the correct statement after step 4. The sin(2x) breaks up into 2sin(x)cos(x), while the cos(2x) breaks up into cos^2(x)-sin^2(x). There are three different variations for the cos(2x) and this just happens to be one of them.

So we can rule out choice B and go with choice A as the final answer.
