Mathematics
1 answer:
noname [10]3 years ago
3 0

Answer:

x²+8x+12, do the distributive property

Step-by-step explanation:

x+6 times x+2 is equal to x(x+2) and 6(x+2) , that will leave you with x²+2x and 6x+12. Add these together to get x²+8x+12

A line passes through the points (-6, 4) and (-2, 2). Which is the equation of the line?
cupoosta [38]

Answer:

\displaystyle y=-\frac{1}{2}x+1

Step-by-step explanation:

The equation of any line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

\displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Two points are given: (-6,4) and (-2,2). Calculating the slope:

\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}

The equation of the line is, so far:

\displaystyle y=-\frac{1}{2}x+b

To calculate the value of b, we use any of the given points, for example (-6,4):

\displaystyle 4=-\frac{1}{2}(-6)+b

\displaystyle 4=3+b

Solving:

b = 1

The equation of the line is:

\boxed{\displaystyle y=-\frac{1}{2}x+1}

We can see none of the choices is correct.

Find the missing variable for a parallelogram:
irakobra [83]
Since the formula to find the area of a parallelogram is base times height (A=bh), and you have been given the area and base already, you can set up an equation. Let h=height in this formula. h x 3.4 = 25. Using this formula, to find the height, you would divide 25 by 3.4 and get approximately 7.35 inches. So, your height= 7.35in. Hope this helps!

Michael: (a)(b)(c)
irinina [24]

Answer:

Ladonna: a + c + b

Step-by-step explanation:

-The commutative property in addition states that the order of arrangement of the integers to be added has no effect on their sum such that:

x+y=y+x

-Since the alphabet follows the order a,b, c....

Only Ladonna rearranged to change this order to show the commutative property.

-Hence, Ladonna wrote the expression correctly.

*The commutative property should not be confused with the associative property.

-The latter allows you to change the order and terms within the closed parentheses while retaining the answer.
