Answer:

The answer is C

Step-by-step explanation:

When you expand the 2 binomials, you get

(-5x + 3)(6x - 2) you get the following 4 terms.

-30x^2 + 18x + 10x + 6 Combine the middle 2 terms

-30x^2 + 28x + 6

The answer is either A or C. I can't tell you why B and D are there. I don't know why anyone would choose - 15x^2 but that is not correct.

So you now have to find out which is true for the domain. There are no values that this quadratic can't have for its domain, so A isn't true. The answer is C

The length of a rectangle is two more than twice the width. the perimeter is 58ft. what is the area of the rectangle?

goldenfox [79]

58/2 = 29

w +2w+2 = 29

3w+2 =29

3w = 27

w = 27/3 = 9

width = 9

length = 2*9=18+2 = 20

20+20+9+9 = 58

Length = 20 feet

width = 9 feet

What is the answer?

mezya [45]

Answer:

18.1 cm

Step-by-step explanation:

AD segment breakup: 11=4+7

Pythagorean Theorem:

7^2+b^2=16^2

49+b^2=256

x^2=207

b=sqrt(207)

b=3sqrt(23)

Pythagorean Theorem:

11^2+3sqrt(23)^2=c^2

121+207=c^2

328=c^2

18.11=c

So the length of AC is around 18.1 cm
