X * y = 50
y = 50 / x
S = x + y = x + 50 / x
S` = 1 - 50 / x²
1 - 50 / x² = 0
50 / x² = 1
x² = 50
x = √ 50 = 5 √2
y = 50 / 5√2 = 5 √2
Answer:
Those numbers are: x = 5√2 and y = 5√2.
Answer:
322 feet
Step-by-step explanation:
first lets plug in our value for s in the equation
.05(70)^2+ 1.1(70)
we then sqaure 70 to get
.05(4900) + 1.1(70)
Then multiply to get
245 + 77
then add to get
322 feet
<h3>Linear expression represents the missing length</h3>
<em><u>Solution:</u></em>
The perimeter of the triangle shown is represented by the expression 10x - 1
The lengths of two sides are given: 3x + 1 and 5x - 2
We have to find the length of third side
We know that,
perimeter of the triangle = sum of length of all three sides
10x - 1 = 3x + 1 + 5x - 2 + third side
10x - 1 = 8x - 1 + third side
third side = 10x - 1 - 8x + 1
third side =2x
2x has variable x and its power is 1
Linear expression is an algebraic expression where the power of variable is equals to 1
Thus linear expression represents the missing length
