4/10 is also equal to 2/5 and 2+2 equals four therefore you would get 4/5 as your final answer
Answer:

Step-by-step explanation:
The equation of a parabola in vertex form is
y = (x - h)² + k (h, k) are the coordinates of the vertex
Given y = x² + 7x - 5
To express in vertex form use the method of completing the square
add/subtract ( half the coefficient of the x- term )²
y = x² + 2(
)x +
-
- 5
y = (x +
)² -
- 
y = (x +
)² - 
Hence
a =
and b = - 
Answer:
Cost of 11 cans of Dog food is $9.57
Step-by-step explanation:
Cost of 5 cans of dog food = $4.35
So to find out the cost of 11 cans of dog food at the same price, we need to calculate the price of 1 can of dog food.
<u>Calculation for finding out cost of 1 can of dog food</u>
The price $4.35 which is given is the price of 5 cans
So to find the cost of 1 can, we need to divide the given price by 5
5 Cans of dog food = $4.35
1 can of dog food = 4.35 ÷ 5
1 can of dog food = $0.87
<em><u>Now to find out the price of 11 cans, we will multiply the price of 1 can with 11</u></em>
Cost of 11 cans = 11 × $0.87
= $9.57
Answer:Every square is a rhombus, and a rhombus can be a square, if all its angles are 90 degrees. Thus, a rhombus can be a rectangle (if the angles of the rhombus are all 90 degrees), and a rectangle can be a rhombus (if the sides of the rectangle are all equal length).
