Answer:
6/25 24%
Step-by-step explanation:
The sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11
<h3>Sum of expressions</h3>
Expressions are equations separated by mathematical signs. This expressions are known to contains certain unknowns
Given the following expression
10x^2 +7x+6 and 6x + 5
We are to take the sum of both expression to have:
f(x) = 10x^2 +7x+6 + 6x + 5
Collect the like terms
f(x) = 10x^2 + 7x + 6x + 6 + 5
f(x) = 10x^2 + 13x + 11
Hence the sum of the given expression expressed as a quadratic equation is 10x^2 + 13x + 11

It is c. If you do the equation it is -1 1/4
Answer:
17 512 dm3 27 28 dm3 37 43 dm3 47 52 92 cm3 57 42 m3
Step-by-step explanation:
17 volume= 8x8x8= 512 dm3
27 volume= 3.5x4x2= 28m3
37 volume= 4x2, 5x4.3= 43 dm3
47 volume= 18x14x21= 5292 cm3
57 volume= 4x3x3.5= 42 m3
the volume cuboid = length x width x height )
Mean is the average. to find mean, you add all the numbers and divide it by how many numbers there are.
68 + 75 + 85 + 80 + 75 + 82 = 465
There are 6 numbers. That means you have to divide 465 by 6 to get the mean.
Divide:
465 / 6 = 77.5
The answer is D. 77.5
