Answer:
650,000 cm²
Step-by-step explanation:
10x6.5=65 METERS squared. They want it in CENTIMETERS squared.
65m² = 650,000cm²
Answer:
Well, I don't know all of them but if you really want to know enter it in a calculator and it'll show (hey, I rhymed lol)
pi = 3.141592654....
Hope that helps and have a great day!
I believe it is the commutative property of multiplication. Commutative property is you can put the numbers in any order and it will have the same end result. I got multiplication because it is multiplication.
Hope this helps!
First lets distribute the 5x
5x^2 + 30x = -50
Lets divide every term by 5
x^2 + 6x = -10
To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9
Add that to both sides of the equation
x^2 + 6x + 9 = -1
Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)
(x+3)^2 = -1
Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i
Answer:
40 degrees
Step-by-step explanation:
so, a triangle is 180 degrees. you know that one angle is 60 degrees.
180= 60+ 2x + x
this is the equation of the triangle
120=3x
simplify
40=x
x= 40 degrees
hope this helps :)
