Answer:11 and 12 is g and g and answer 13 is 5.36487494991
Step-by-step explanation:
Answer:
x²+6x+9=0
x²+3x+3x+9=0
x(x+3)+3(x+3)=0
(x+3)(x+3)=0
either
x+3=0
x=-3
or
x+3=0
x=-3
Step-by-step explanation:
next method
x²+6x+9=0
x²+2×x×3+3²=0
it is in formula of (x+y)²
(x+3)²=0
x+3=√0
x+3=0
x=-3
Answer:
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
The product of the gradients of perpendicular lines is -1.
Gradient of given line= 3.
(Gradient of line)(3)= -1
3m= -1
m= 
subst. m= into the equation:
To find the value of c, substitute a coordinate.
When x=0, y=4,
Thus the equation of the line is 
.
1.09÷3= .3633 each
4.49÷12= .37416 each
8.78÷24= .3658 each
so the first one
Answer:
<u>The honey costs US$ 0.45 per ounce</u>
Step-by-step explanation:
1. Let's review the information given for solve the question:
Cost of the honey at the supermarket = US$ 5.40
Weight of the honey bought by the customer = 12 ounces
2. This is the formula to find out the cost per ounce:
Cost per ounce = Cost of the honey/Weight of the honey bought by the customer
Cost per ounce = 5.40/12
Cost per ounce = 0.45
<u>The honey costs US$ 0.45 per ounce</u>
