Answer:

Step-by-step explanation:

3x2 + 8x + 4

A =

1

2

(b1 + b2)(height)

A =

1

2

(3x + 3x + 4)(x + 2)

A =

1

2

(6x + 4)(x + 2)

A =

1

2

(6x2 + 16x + 8)

A = 3x2 + 8x + 4

The answer is A

The area of a trapezoid is calculated by the equation,
                          A = 0.5(b₁ + b₂)h
where b₁ and b₂ are the bases and h is the height. When we substitute the given expression for the dimensions in the given,
                          A = 0.5(4x + 2x)(x - 6)
                          A = 0.5(6x)(x - 6) = 3x² - 18
Thus, the answer is letter A.

how many solutions does the graph above show? <br> a. one <br> b. none<br> c. infinite
dmitriy555 [2]

Answer:

infinite

Step-by-step explanation:

The line can be represented by the equation y=-2/3x-2 since there are no other lines it would be infinite. if there was a line with the same slope and a different y-intercept the answer would be none as the lines never intersect.  for the equation there are ifinitly many!  

     for example any point that that lone touches is a solutions so there is not one but many answers.

the greatest common factor gcf of 2 monomiald is 3x^2y. One of the monomials is 3x^4y . Which couod be the other monomial.
fomenos
While I cannot see your answer choices, the correct answer would be one that has a coefficient that is a multiple of 3 and has an x raised to an exponent of no more than 2.  It could have any other variables in it.

The reason this has to be is because of the GCF.  Since 3 is part of the GCF, and the other monomial has a coefficient of 3, this means the missing monomial must be divisible by 3 as well.

Since x² is part of the GCF, the missing monomial must contain x².  However, if it were to contain x³ or anything larger, the GCF would have x with a higher exponent.

Two sides of a triangle have lengths of 18 and 29 units. if the third side has an integer length, what is the positive differenc
Andru [333]
Triangular inequality:  Length of third side must be less than the sum of the lengths of the other 2 sides.
x < 18 + 29
x < 47

so Maximum length of third side is 46 units.

Also 29 < 18 + x
x > 11    so minimum length = 12

Difference  = 46-11 = 35
