Answer:

2x(3 {x}^{2}  - 4x) + 3( {x}^{2}  - 4x + 6) \\ 6 {x}^{3}  - 8 {x}^{2}  + 3 {x}^{2}  - 12x + 18 \\ 6 {x}^{3}  - 5 {x}^{2}  - 12x + 18

a = 6 \\ b = -5 \\ c =- 12 \\ d = 18

Rasek [7]
Michelle: x
Ian: 5x
Joe: 7x
Michelle + Ian + Joe = 208 berries
x + 5x + 7x = 208
Combine like terms: 13x = 208
Divide both sides by 13: x = 16
Joe = 7x = 7*16=112
Joe picked 112 berries

(x+ 3/8 ​ ) 2 + y 2 =1<br> what is the radius &amp; units?
Pani-rosa [81]

The radius of the circle of the circle equation (x + 3/8)^2 + y^2 = 1 is 1 unit

<h3>How to determine the radius of the circle?</h3>

The circle equation of the graph is given as:

(x + 3/8)^2 + y^2 = 1

The general equation of a circle is represented using the following formula

(x - a)^2 + (y - b)^2 = r^2

Where the center of the circle is represented by the vertex (a, b) and the radius of the circle is represented by r

By comparing the equations (x - a)^2 + (y - b)^2 = r^2 and (x + 3/8)^2 + y^2 = 1, we have the following comparison

(x - a)^2 = (x + 3/8)^2

(y - b)^2 = y^2

1 = r^2

Rewrite the last equation as follows:

r^2= 1

Take the square root of both sides of the equation

√r^2 = √1

Evaluate the square root of 1

√r^2 = 1

Evaluate the square root of r^2

r = 1

Hence, the radius of the circle of the circle equation (x + 3/8)^2 + y^2 = 1 is 1 unit

What is the measure of _Y, in degrees?
Pachacha [2.7K]

Answer:

C. 116º

Step-by-step explanation:

Both sides are congruent, so the triangle is an isosceles triangle. So angle Z will have to be congruent to angle X. Add together the two angles, (32 + 32) and subtract the sum from 180º since all triangles add up to 180º.

32 + 32 = 64

180 - 64 = 116
