If exactly as written
-16128x^2y
if x^4 x^3 and y^2
-672x^7y^2
Answer:
2x +7
Step-by-step explanation:
2x2 is multiplication , so u multiply ,minus the 2x would be 4x -2x , so it will give 2x + 7 as final asnwer
The missing side of the fence measures 15 ft
The perimeter of the fence is 40 ft
The area inside the fenced in section is 60 ft²
The fence is triangular and a right triangle.
<h3>Right triangle:</h3>
A right triangle has one of its angle as 90 degrees. Therefore, the sides can be found using Pythagoras theorem.
c² = a² + b²
17² - 8² = b²
b = 15 ft
AC = 15 ft
perimeter of the triangle = 15 + 8 + 17 = 40 ft
Area of the triangle = 1 / 2 × 15 × 8 = 60 ft²
Therefore,
The missing side of the fence measures 15 ft
The perimeter of the fence is 40 ft
The area inside the fenced in section is 60 ft²

Answer: $4
Step-by-step explanation:
In this situation let's set up a proportional relationship .
Now solve by cross multiply
0.5x = 2 Divide both sides by 0.5
x = 4
This means that if Emily bikes 10 miles, her mother will donate $4.
Answer:
y = -9 / 7x + 109 / 7
Step-by-step explanation:
To find the equation of any line, you must find the slope and y-intercept (when writing in slope-intercept form). In this case, we can find both of these values by using the two coordinate pairs that are given:
Slope - the change in y over the change in x
- 9 / -7 = -9 / 7
- slope = -9 / 7
- y-intercept - when x = 0
Right now, since we have the slope, we know the equation will look like this: y = -9 / 7x + b, b is what we are trying to find, the y-intercept. To find b, we can substitute a given coordinate pair that we know will fit this line and then solve:
- 13 = -9 / 7 x 2 + b
- 13 = -18 / 7 + b
- 91 / 7 + 18 / 7 = b
- 109 / 7 = b
After finding both the slope and y-intercept, we can now combine them together to form the equation of the line:
y = -9 / 7x + 109 / 7
Hope this helps!!
