Answer: x=3

I got to the answer by doing simple math. Both sides must be even.

5x-4

5(3)-4= 15-4 = 11

x+8

3+8= 11

So x=3

Multiple the polynomial (4x^2 + 4x + 6)(7x + 5)

Mazyrski [523]

Answer:

28 x³ + 48 x² + 62 x + 30

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the polynomial equation

(4 x² + 4x +6)(7x+5)

Multiply

⇒ 4 x² ( 7 x+5) + 4 x ( 7x+5) + 6 (7x+5)

⇒ 28 x³ + 20 x² + 28 x² + 20 x + 42 x + 30

⇒ 28 x³ + 48 x² + 62 x + 30

A litter of 9 kittens available for adoption at the Humane Society has four orange kittens and five black kittens. A family come

Dovator [93]

Answer:

B

Step-by-step explanation:

What is required is the probability of selecting one orange and one black kitten.

outcomes ( 1 O and 1B) = 4C1 * 5C1

Total outcomes = 9C2

Note: the order of color does not matter it is simply a matter of selection hence only combinations are made NOT permutations.

P (1O and 1B) = outcomes ( 1 O and 1B) / Total outcomes

P (1O and 1B) = (4C1 * 5C4) / 9C2 = 0.5556

Rectangle WXYZ is shown on a coordinate plane. On a coordinate plane, a rectangle has 4 points. Point W is (1, 1), point X is (1

Temka [501]

Answer:

the length of the side XY is 4 units

Step-by-step explanation:

To find the length of side XY, what we do is to find the distance between the points X and Y

To find this distance, we employ the use of the formula for finding the distance between two points on a Cartesian plane.

Mathematically, the distance d which represents the length XY is given by;

d = √{(x2-x1)^2 + (y2-y1)^2}

Where point X represents the coordinates (x1,y1) = (10,1) while point Y represents the coordinates (x2,y2) = (10,-3)

Plugging these values into the formula, we have;

d = √{(10-10)^2 + (-3-1)^2}

d = √{(0)^2 + (-4)^2}

d = √(0 + 16)

d = √(16)

d = ± 4

but since distance cannot be negative, we ignore the -4 and thus we choose 4 units as the length between the points XY

Points A, B, and C are plotted on the unit circle.

sertanlavr [38]

Answer:

E. x-coordinate of point C

Step-by-step explanation:

Consider the diagram of the unit circle which has been drawn and attached.

Using a calculator in radians, $cos (\pi)=-1$

On the unit circle, out of points A, B and C, the point -1 is at point C.

Point C is located at (-1,0).

Therefore, $cos (\pi)$ is the x-coordinate of point C.

The correct option is E.
