If x=5 then the answer would be 18. 3 times 5 is 15 +3=18
Answer:
the width=15; the length=20
Step-by-step explanation:
1. to solve the given equation: x²+5x-300=0;
x₁= -20; x₂=15, where 'x' can be only positive value. It means x=15;
2. according to the condtition the length is more, it means 15+5=20.
3. the width is x=15; the length is 20.
Answer:
$38.30
Step-by-step explanation:
Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
Sum of the numbers = $20 + $45 + $30.50 + $46 + $50 = $191.50
Total number = 5
Mean = $191.50 / 5 = $38.30
Answer:
<h3>
</h3>
Step-by-step explanation:
x² - 10x + 25 = 35
Move 35 to the left side of the equation
That's
x² - 10x + 25 - 35 = 0
x ² - 10x - 10 = 0
Using the quadratic formula solve the equation
That's
<h3>
</h3>
From the question
a = 1 , b = - 10 , c = - 10
Substitute the values into the above formula and solve
That's
We have the final answer as
