Answer:
34
Step-by-step explanation:
(3 + 5i)(3 - 5i) = 9 - 25i^2
because i^2 = -1 9 - 25i^2 = 9 - 25x-1 = 34

6 inches of yarn make 1 bracelet.
5 feet of yarn make how many bracelets?
1 foot = 12 inches
5 feet = 12 * 5 inches = 60 inches
6 inches of yarn make 1 bracelet
60 inches of yarn make x bracelets
6/1 = 60/x
Cross multiply
6x = 60
x = 10
60 inches yarn make 10 bracelets.
Answer:
B
Step-by-step explanation:
Given
y = (x - 3)(x - 13)
Find the zeros by setting y = 0, that is
(x - 3)(x - 13) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 13 - 0 ⇒ x = 13
The vertex lies on the axis of symmetry which is located at the midpoint of the zeros, thus the x- coordinate of the vertex is
=
=
= 8
Substitute x = 8 into the equation for the corresponding y- coordinate
y = (8 - 3)(8 - 13) = 5(- 5) = - 25
vertex = (8, - 25 ) = (u, v) → with v = - 25 → B
Answer:
<h2>
The more complex answer:</h2>
x: number of days
y: number of total pounds.
For 12 elephants, we have the expression is:
Then, for the given number of days, we have x = 5.
Substituting the value of x we have:
an expression to represent the number of pounds of food a herd of 12 elephants eat in 5 days is:
<h2>
the easy answer:</h2>
The find the answer for this particular question you would you would multiply 12 by 300 which is 3600, and you would then multiply that by 5 which is 18000
8=3w+2.5m
W is weeding and M is mowing
If you need to solve that equation, the most work she could get done in one day is weeding 1 yard and mowing 2 yards
