Answer:

5x^4 - 6x^3 - 11x^2 + 14x

Step-by-step explanation:

(5x^4 - 3x^3 + 6x) - (3x^3 + 11x^2 - 8x)

= 5x^4 - 3x^3 + 6x - 3x^3 + 11x^2 - 8x

= 5x^4 - 3x^3 - 3x^3 - 11x^2 + 6x + 8x

= 5x^4 - 6x^3 -11x2 + 14x

What is the surface area of the figure?
oksano4ka [1.4K]
We have 8 sides to calculate, it will be hard to explain which side I'm calculating without marking on the picture. 

We will start with the front facing side. We can break this up into an 8ft x 8ft square, and a 14ft x 6ft rectangle. The area equals: 
8ft x 8ft + 14ft x 6ft = 148ft^2

The front facing is the same area as is back facing counterpart so we can multiply the surface area by 2:
148ft^2 x 2 = 296f^2

Adding the bottom surface area 6ft x 14ft:
6ft x 14ft + 296ft^2 = 380ft^2

Adding the right side 6ft x 14ft:
6ft x 14ft + 380ft^2 = 464ft^2

Adding the left side 8ft x 6ft:
8ft x 6ft + 464ft^2 = 512ft^2

Adding the 3 sides on the top 8ft x 6ft (top facing), 6ft x 6ft (top facing), and 6ft x 6ft (left facing):
<span>8ft x 6ft + 512ft^2 = 560ft^2
</span><span>6ft x 6ft + 560ft^2 = 596ft^2
</span>6ft x 6ft + <span>596</span>ft^2 = 632ft^2

Therefore the answer is C, 632 ft^2.

Find the area of the trapezoid with a base of 19 inches, height 12.6 inches and base 29.2 inches
kati45 [8]
A trapezoid is a quadrilateral with two parallel sides of different lengths. This means that any of the two sides can be called a base, and that the trapezoid is unique because it has two bases.
 the formula for finding the area of a trapezoid is
 [(b1 + b2) x h] / 2
 Substituting the values:
 ((19 + 29.2) * (12.6)) / 2
 303.66 in ^ 2
 Answer: 
 the area of the trapezoid is: 
 303.66 in ^ 2

Goes through (1,4) is parallel to y=3x-7
user100 [1]

Answer:

y = 3x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 7 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation

To find c substitute (1, 4) into the partial equation

4 = 3 + c ⇒ c = 4 - 3 = 1

y = 3x + 1 ← equation of parallel line
