Step-by-step explanation:
hopefully that helps you
Answer:
x times y
Step-by-step explanation:
k is the value of x times y
Assuming "i" is an imaginary unit:
The information you would need to create a two-variable equation is how much was her allowance and how much money did she have. Also you would need to know how many arcade games she played and how much each one cost and how many times she rode the Ferris wheel and how much each ride cost.
Hope this Helps!!
Answer:
length of side = 10x + 3
Step-by-step explanation:
The area of a square = s² ( s is the length of the side )
given
A = 100x² + 60x + 9 ← perfect square in the form
(a + b)² = a² + 2ab + b²
100x² = (10x)² ⇒ a = 10x
9 = 3² ⇒ b = 3
and 2ab = 2 × 10x × 3 = 60x, hence
100x² + 60x + 9 = (10x + 3)²
s = 
= 10x + 3 ← length of side
