You can think of a square as two isosceles right angle triangles and use Pythagoras.

x^2 + x^2 = 22^2
x^2 + x^2 = 484
2x^2 = 484
x^2 = 242
x = 11√2

One side of the playground is 11√2 m long.

The sum of four consecutive integers is 386. What is the fourth integer?
Licemer1 [7]

The 4 consecutive integers are 95, 96, 97 and 98.

The fourth integer is 98.

<u>Step-by-step explanation:</u>

Let us consider the 4 consecutive integers to be 'x' , 'x+1' , 'x + 2' , 'x + 3'  

The sum of the 4 consecutive integers= 386

x + (x+1) + (x+2) + (x+3) = 386

4x + 6 = 386

4x = 380

x = 380/4

x = 95

x+1 = 96

x+2 = 97

x+3= 98

The 4 consecutive integers are 95, 96, 97 and 98.

The fourth integer is 98.

Can someone please help super short
insens350 [35]

Answer:

542, 543, 544, 545.

Step-by-step explanation:

Divide 2174 by 4 = 543.5  

(because there are 4 integers) 543.5 is not an integer.

However, one of the four integers is 543.

Write down four consecutive numbers that include 543 and add them:  

like 541+542+543+544 =. if that is 2174, you have the answer, if it's too low, try moving up one number, like

542+543+544+545 = if it's still too low, move up one number again  

543+544+545+546=  

You only have to do that a max of 3 times to get the answer.

The four consecutive integers are  

542, 543, 544, 545.

<em>good luck, hope this helps :)</em>

Figure D could be formed from the net.

(bottom right)

-Because-

The net says that the middle shape (the bottom face) is 14 long, and it is 8 tall. So the only option that makes sense is the bottom right!

Y= (x+3)^2+10 put into binomial form
tensa zangetsu [6.8K]
None of the answers are correct
(x+3)^2 + 10           first you factor out the (x+3)
(x+3)(x+3) + 10
x^2 + 6x + 9 +10    simplify
x^2 + 6x + 19
