Answer:
x = 5 is the right answer.
Step-by-step explanation:
As we know sum of all angles in a triangle is 180°.Therefore in this question we will form an equation.
Sum of all the angles of a triangle = 180
91 + 10x - 4 +8x +3 = 180
90 + 18x = 180
18x + 90 - 90 = 180 - 90
18x = 90
x = 90÷18 = 5
Therefore x = 5 is the right answer.
Answer:
23x-8
Step-by-step explanation:
Find the difference between the X and Y values goven:
10 - 1 = 9
12 - 3 = 9
15 - 6 = 9
The difference is 9, so the rule is subtracting 9 from the x value:
y = x -9
Now find Y when x is 20:
y = 20-9
y = 11
We are given the following information:
the sum of the first number cubed and the second number is 500
their product is a maximum
We are looking for the 2 missing numbers.
To answer this, let's represent the two numbers as x and w.
From the given, we can form the following equation:

We can then express y as:

We can express their product as:

To find the maximum value of x, let's solve for the derivative of -x^4 + 500 x.

Then we solve for the value of x where f'(x) = 0.

Then we use x = 5 to solve for the second number, w.

Therefore, the two numbers are 5 and 375.
