Answer:
Step-by-step explanation:
1. Move the 6 to the other side: x^2 +4x =6
2. Square half the coefficient of the x term: (4/2)^2 = 4
3. Add this 4, and then subtract this 4, from x^2 + 4x:
x^2 +4x + 4 - 4 =6
4. Rewrite this perfect square as the square of a binomial:
(x + 2)^2 - 4 = 6
5. Add 4 to both sides: (x + 2)^2 = 10
6. Find the sqrt of both sides: x + 2 = √
Answer:
8
Step-by-step explanation:
In 2 hours
1 cook makes 10 large cakes
24/10 = 2.4
You need 3 cooks to make the large cakes.
In 2 hours
1 cook makes 28 small cakes
130/28 = 4.64
You need 5 cooks to make the small cakes.
3 + 5 = 8
Answer: 8
Subtract 4 from both sides of the equation
you will end up with 2/7x=4
next multiply 7x by both sides
you will end up with 2=28x
next divide 28 from both sides
you will end up with x=1/14 in
fraction form. Hope this helps.
