Answer:
See explanations below
Step-by-step explanation:
Given the algebraic expression 2x4– 5x3 + 4x. + 7,
a) The degree is the highest power of x in the equation, from the equation we can see that the highest power of x is 4. HEnce the degree of the equation is 4
b) The terms we have are 2x^4, -5x^3, 4x and 7. In counting, we can see that we only have 4 terms in the equation hence the number of terms is 4
c) The constant term si the term without the variable x. From the equation the only term without variable x is 7. Hence the constant term is 7
d) The number attached t x is known as its coefficient. The number besides x is 4 frim the equation. Hence the coefficient of x is 4.
e) The numerical coefficient of -5x^3 is -5 since the constant value attached to x^3 is -5
The slope is y=3x-2, or if you had to rewrite it, 3x-2 is the slope. The y intercept could be found using the previous formula, y=3x-2. If x were to be equal to 5 for example, you would have to multiply that by 3, then subtract it by 2, and you get your y intercept, which would equal 13 (THIS IS AN EXAMPLE).
The mean of the numbers is 11 now all you have to do is take 11 and subtract it from the squared difference.
Answer:
45.8
Step-by-step explanation:
We need to find the surface area for this entire figure!
We can see that this is a pyramid here - we must find the area of the 3 triangles and the base triangle at the bottom.
The 3 triangles building up the pyramid are all equal to each other.
To find the area of a triangle, use 

Round to the nearest tenth: 45.75 -> 45.8
The correct answer is:
D. 20.4 cm - 16.8 cm (attached)
The triangular prism is similar to the described prism.
