If B is the midpoint of line AC, AC = CD, AB = 3x+4, AC=11x-17, and CE = 49, find DE. (Show work)
larisa [96]

Answer:

2(3x+4) = 11x-17

6x+8 = 11x-17

25=-5x

x=-5

11x-17

55-17

38

AC = 38

CD = 38

49-38 = 11

DE = 11

Let me know if this helps!

Josh made 8 3/4 cups of jello. if he serves it in 1/2 cup servings, how many people can he serve?
juin [17]

Answer: 17 people

Step-by-step explanation:

You divide 8 3/4 and 1/2 and you get 17 1/2

And since the question asks how many people can he serve you use the whole number because its not fair if you give a full serving to a person and half a serving to another.

A square corner of 16 square centimeters is removed
oee [108]

Option C:

Area of the remaining paper = (3x – 4)(3x + 4) square centimeter

Solution:

Area of the square paper = 9x^2 sq. cm

Area of the square corner removed = 16 sq. cm

Let us find the area of the remaining paper.

Area of the remaining paper = Area of the square paper – Area of the corner

Area of the remaining = 9x^2-16

                                     = (3x)^2-(4)^2

Using algebraic formula: a^2-b^2=(a+b)(a-b)

                                     =(3x-4)(3x+4)

Area of the remaining paper = (3x – 4)(3x + 4) square centimeter

Hence (3x – 4)(3x + 4)  represents area of the remaining paper in square centimeters.

Factorize the following expression ab-a-b+1
dolphi86 [110]

Group 'em together

a b − a + 1 − b

a b − a = a ( b − 1 )

Notice that there will be a 1 as without it it'll simply be  ab

1 − b = 1 ( 1 − b )

Notice that it doesn't match with the upper one... so we'll change the signs

1 ( 1 − b ) = − 1 ( b− 1 )

(try to multiply them now!!

Jot them down in one expression

a ( b − 1 ) − 1 ( b − 1 )

You get!!!!!!

( a − 1 ) ( b − 1 )
