Answer:
<h3>p(+)q=SQR(p^2+q^2)</h3>
8(+)6=SQR(8^2+6^2)
SQR(64+36)
SQR(100)
=10
Step-by-step explanation:
p + Q is equal to square root of p square + Q Square
sqr means square root
The answer is this: $3.60
4 x 10 = 40 - 0.4 = 3.6
Answer:
14.99
Step-by-step explanation:
The area of a triangle is A=1/2b*h
You have the base (b) and you have the area (A)
So, if you plug in what you know, you get this:
45.5=1/2*10*h
Simplify it:
45.5=5h
Now solve for h
Divide by 5 to get h alone:
9.1=h
Your height is 9.1cm
Hope this helps :)
To complete the square (x+2/5)^2 it would be x^2+(4/5)x+4/25
