1. The area is l * w, so just multiply 5x by 5x. Replacing x with 2.2 gets:
(5 * 2.2) * (5 * 2.2)
11 * 11
= 121
So, the area of the square when x = 2.2 centimeters is 121 sq cm.
2. The expression for this equation would be:
6(y + 4)
And using the distributive property on this to get the simplified expression, just multiply both y and 4 by 6.
6 * y + 6 * 4
6y + 24
So, your expression is 6y + 24.
3. For this one, let's make y's value 3.5 instead of 3 1/2 to make it easier to solve.
We just use the above expression to solve.
6 * 3.5 + 6 * 4
21 + 24
= 45
So, the area of the rectangle when y = 3 1/2 is 45 sq in.
4. For this last one, let's use the formula w = A/l to form an expression that will represent the width.
w = 8w + 18/2
Now, let's simplify it by dividing 8w and 18 by 2.
w = 8w/2 + 18/2
w = 4w + 9
So the expression to represent the width of the rectangle is 4w + 9.
Hope this helped!

Answer:
F=0.46N
Step-by-step explanation:
∝
,
(32 + 90 + 92 + 82 + 64 + x) / 6 = 85
(360 + x) / 6 = 85
360 + x = 85 * 6
360 + x = 510
x = 510 - 360
x = 150 <===
Answer:
0.1 cents per ounce
Step-by-step explanation:
You know that you paid 88 cents for the whole bottle of ketchup and the whole body contains 9oz of ketchup. Every one ounce is equal to 9.8 cents. You simply need to divide the total amount of the item by the weight (9 ounces) to get 0.09 or 0.1 when rounded.
