Complete the following: (2x +3y)^2 = (2x)^2+2(2x)(3y) +(____)^2
FrozenT [24]

Answer:

Complete function will be  (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

Step-by-step explanation:

We have given equation (2x+3y)^2=(2x)^2+2\times (2x)\times (3y)+..........^2

We have to find the function in place of blank space and complete the function

We know the algebraic equation (a+b)^2=a^2+b^2+2ab

So (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

So in place of blank pace there will be (3y)^2

And complete function will be  (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

35 degrees + 90 degrees + k
spayn [35]

Answer:

k would be 55

Step-by-step explanation:

35+90=125 and assuming that you're looking for a supplementary angle, the total must equal 180 so subtract 180-125  and you get k=55

Lorico [155]

Answer:

3142 feet

Step-by-step explanation:

first, find the circumference of the wheel.

approx 75.4

every one rotation you travel approximately 75.4 inches

75.4 x 500 =37,700

37,700/12 = feet traveled

3141.6... feet

rounded = 3142

10 POINTS!! HELP ASAP!! What is the length of AC?
My name is Ann [436]

Answer:

D

Step-by-step explanation:

Δ CED and Δ CAB are similar thus the ratios of corresponding sides are equal, that is

\frac{CE}{CA} = \frac{ED}{AB} , substitute values

\frac{x}{156-x} = \frac{7}{84} = \frac{1}{12} ( cross- multiply )

12x = 156 - x ( add x to both sides )

13x = 156 ( divide both sides by 13 )

x = 12

Thus

AC = 156 - x = 156 - 12 = 144 → D
