Answer:
you pick similar sides from both the triangles and try and divide or find common multiples. for ex if the sides are 3 and 9, you can find that the scale factor is 3 since 9/3 is 3
Step-by-step explanation:
Answer:
4π or about 12.56
Step-by-step explanation:
The circumference of a circle is calculated with diameter so we first need to find the diameter. Going from radius to diameter can be done by multiplying by 2, therefore 2*2=4 so the diameter is 4.
Now that we have the diameter we need to use the formula for circumference which is c=4*π. Because the question doesn't state to use 3.14 to multiply then you would usually use 4π as your answer but if you were to use 3.14 then you would get a circumference of 4*3.14=12.56.
Answer:
no asnwer
Step-by-step explanation:
first step:
-5x+y+5z=27
+ 5x+5y-4z=-12
which is
6y+z=15
add -6y-z=-16
which will be 0=-1
this means that there is no answer and that the statement is false.
hope this helped!
Answer:
(x-6)(x-6) or (x-6)^2
Step-by-step explanation:
x^2-12x+36=(x-6)(x-6)
Just find two numbers that when they multiply, you get the third term,
which is 36 in this case. And when they add up, you get the second term,
which is -12 in this case. You can also check the answer by multiplying.
(x-6)(x-6)=x^2-6x-6x+36=x^2-12x+36
