3 0

Answer:

6x + 2w - y

Step-by-step explanation:

  1. Remove unnecessary parentheses

5x + 2w + ( x - y)

or when there is a "+" in front of an expression in parentheses, the expression remains the same.

2. collect like terms

6x + 2w - y

so your answer will be 6x + 2w - y

Geometry. Answer the question in the photo.
Elanso [62]

Answer:

5

Step-by-step explanation:

Since, A, B, C, D are collinear.

\implies A - B - C - D \\  \therefore \: AD = (AB + BC) + CD \\  \therefore \: 18 = AC + CD..  (\because AB + BC =AC) \\  \therefore \: 18 = 8 + CD \\  \therefore \: 18  - 8 = CD \\ \therefore \: 10 = CD \\  \\  \because \: BC + CD = BD \\ BC  = BD - CD \\  BC  = 15 - 10 \\ BC  = 5 \\

The width of the triangle is 3/4 the length. The perimeter is 252cm. What is the width of the triangle.
ICE Princess25 [194]

Answer:

C).  54 cm.

Step-by-step explanation:

I think you mean a rectangle .

If the length is x then the width = 0.75x   (because 3/4 = 0.75).

Perimeter = 2*length + 2*width.

252 =  2x + 2*0.75x

252 = 2x + 1.5x

252 = 3.5x

x = 252 / 3.5

= 72  which is the length,

The width = 3/4 * 72

= 54 cm.

Is the ordered pair
FrozenT [24]

Answer:

no, because for x=-3, y would have to be -31

Step-by-step explanation:

boy oh boy (or girl oh girl) - you wrote this in a horrible, horrible format.

I can only guess what your problem and the fitting answer would be.

y = -2×x^2 + 3×x - 4

-4 = -2×(-3)^2 + 3×(-3) - 4

-4 = -2×9 - 9 - 4

-4 = -18 - 9 - 4

-4 = -31

and that is wrong. for (-3,-4) to be on the graph of the function, y would have to be -4 when using x=-3 in the function. but y = -31 for x= -3.
