<h3>Answer: Choice B</h3>

Consider that choice B is the same as saying 2x^2+1x^0.

The exponents 2 and 0 are both even, which is sufficient to say that the entire polynomial function itself is also even.

Something like choice A expands out and simplifies to x^2-2x+2, and that's equivalent to saying x^2+2x^1+2x^0. The presence of the x^1 term, with its odd exponent, is what makes choice A not even (it's not odd either).

Similarly, choices C and D also have exponents of 1, so they aren't even either.

Ja'kniya and Alayjah are shopping at the Apple Store. Ja'kniya bought 4 screensavers and 3 Otterboxes for $29. Alayjah bought 6

Katarina [22]

Answer: Each screensaver costs $2 and each Otterbox costs $7.

Step-by-step explanation:

Let x = Cost of each screensaver and y = cost of each Otterbox.

As per given, 4x+3y=29 (i)

6x +2y = 26 (ii)

Divide both sides of (i) by 2 and the multiply it by 3 on sides , we get

9x+3y=39 (iii)

Eliminate (i) from (iii) , we get

5x = 10

⇒ x = 2 [Divide both sides by 5]

Put value of x in (i), we get

4(2)+3y=29

⇒ 8+3y= 29

⇒ 3y= 21

⇒ y =7 [Divide both sides by 7]

Hence, Each screensaver costs $2 and each Otterbox costs $7.

What is the implicit premise in the following argument? Because it is hard to find four-leaf clovers, I will be lucky to find on

Mama L [17]

Answer: Either it is not hard to find four leaf clovers, or i would be lucky to find one.

Step-by-step explanation:

An assumption is any assertion or concept that is taken to be true and on which an argument or argument may be based.

From the argument is centered on the probability of finding a four leaf clover.

It is an already established fact that four leaf clovers are rear to come by so it would require a lot of luck to actually find one.

Solve for b2 in A = h ( b1 + b2 ), if A = 16, h = 4, and b1 = 3.

nlexa [21]

Divide 4 by both sides
Then you get 4=3+b2
Then subtracts 3 from four
You get 1=b2

According to the synthetic division below, which of the following statements are true?

kykrilka [37]

Answer:

Options (A) and (D)

Step-by-step explanation:

We can write the given division as,

$\frac{2x^2+6x-8}{x+5}=2x-4+\frac{12}{x+5}$

Option (A)

When (2x² + 6x - 8) is divided (x + 5), the remainder is 12.

True.

Option (B)

When (2x² + 6x - 8) is divided (x - 5), the remainder is 12.

False.

Option (C)

When x = 5,

2x² + 6x - 8 = 12

2(5)² + 6(5) - 8 = 50 + 30 - 8

= 72

False.

Option (D)

When x = -5,

2(-5)² + 6(-5) - 8 = 50 - 30 - 8

= 12

True.

Option (E)

(x - 5) is a factor of 2x² + 6x - 8

If (x - 5) is a factor value of 2x² + 6x - 8 should be zero.

False.

Option (F)

(x + 5) is a factor of 2x² + 6x - 8

If (x + 5) is a factor then by substituting x = -5 in the expression value should be zero.

But the value is 12.

False.
