Answer:
n = -45
Step-by-step explanation:
(n-5) /10 = -5
Multiply each side by 10
(n-5) /10 *10= -5*10
n-5 = -50
Add 5 to each side
n-5+5 = -50+5
n = -45
I’m pretty sure 30 because you multiply 10x3 I’m sorry if I’m wrong I haven’t done Surface Area in a long time
Let's say you have 1/2 and 4/8
1.) Simplifying
Divide 4/8 by 4 to the numerator and denominator. You should get 1/2 which is equivalent to 1/2
2.) Cross multiplying
Cross multiply 1/2 x 4/8 (you multiply the numerator to the other fraction's denominator).
You should get 1 x 8 = 2 x 4
This simplified is 8 = 8 which is true.
Therefore the two fractions are equivalent. Hope this helps! :)
The answer should be '0' because if you multiply anything times '0' it is still '0'.
Answer:
B. x=1+2i or x=1-2i.
Step-by-step explanation:
The equation is given as;
x²-2x+5=0
complete the square method to find value of x as;
x²-2x = -5
x²-2x + 1 = -5 + 1
x²-2x +1 =-4
( x-1 )² = -4
x-1 = ±√-4 ---------<em>where √-1 = i</em>
x-1 =± 2i
So;
x-1 = + 2i
x= 1+2i
or
x= 1-2i
x= 1-2i
