Find the number to add to x^2-18x
pentagon [3]

Answer:

A. add 81; (x-9)^2

Step-by-step explanation:

The perfect square formula

(a-b)^2=a^2-2ab+b^2

Rewrite expression x^2-18x as follows:

x^2-2\cdot 9\cdot x

So, to form a perfect square, +9^2 is missed.

When we add 9^2=81, we will get

x^2-2\cdot 9\cdot x+9^2=(x-9)^2

Find the area of the kite.<br> 13<br> 12<br> 8<br> 主<br> A=<br> lin²
rewona [7]

Answer:

100㏑²

Step-by-step explanation;

first of all you find the base using the pythagoras theorem

that is, √13² - 12² =√25 = 5

so 5 is the base of the right angle in the big isoceles triangle

so the base of the isoceles triangle is 10 [5 + 5]

so for the first triangle the area is 60㏑²

the second triangle is 40㏑²

therefore 60 + 40 = 100㏑²

Which equation represents the line shown in the graph below?
likoan [24]

The answer is y=2x+5


To get it use point slope by taking two points and solving .


Slope formula


M= y2-y1/x2-x1


With two points


(0,5)(-5,-5)


M= -5-5/-5-0

M= -10/-5

M=2


2 is slope


Now get one of the points

(0,5) And slope to create equation y=mx+b . Now find b


5=2(0)+b

5=b


So now you can put it all together


Y= 2x+5
