Answer:

-30bc + 50bd

Step-by-step explanation:

3a + 5b/3c - 5d = 3a - 5b/3c - 5d

(3c - 5d)(3a - 5b) = (3a + 5b)(3c - 5d)

9ca - 15bc - 15da + 25db = 9ac - 15ad + 15bc - 25bd

9ca -15bc - 15da + 25db - 9ac + 15ad - 15bc + 25bd

9ca and -9ac and -15da and 15ad cancel each other out, so

-30bc + 50db is left

The width of a rectangle painting is 3 in. more than twice the height. A frame that is 2.5 in. wide goes around the painting.

A.
$A=(2h+8)(h+5)$

b.
If h = 12
$A=(24+8)(12+5)=(32)(17)=544$

c.
If h = 15
$A=(30+8)(15+5)=(38)(20)=760$

Solve the following system using the SUBSTITUTION method. x - 3y = 2 2x - 6y = 6

notka56 [123]

ANSWER:

x – 3y = 2 ...(1)
2x – 6y = 6 ...(2)

On solving eq(1), we get

x – 2 = 3y
x – 2/3 = y

Plug the value of x in eq(2)

2x – 6(x - 2/3) = 6
2x – 2(x – 2) = 6
2x – 2x + 4 = 6
0 = 6 – 4
0 ≠ 2

So, given system of equations is not correct.

What is the slope of the line that goes through the points (12,-18) (-15,-18)

AnnZ [28]

Hi!

Step-by-step explanation:

$SLOPE=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{(-18)-(-18)}{(-15)-12}=\frac{0}{-27}=0$

Slope is 0.

The answer is 0.

Hope this helps!

Have a nice day! :)
