We are given a triangle with dimensions of the three sides as :
first side: 10x+3x²-8 feet
second side: 12x feet
third side: (15x+4) feet
Now perimeter of triangle is given by:
Perimeter = sum of three sides
So adding the three sides:
Perimeter = 10x+3x²-8 + 12x +15x+4
combining like terms and simplifying:
Perimeter = 3x²+37x-4
Answer: The perimeter of park will be (3x²+37x-4) feet.
Answer:
x = -7/2
Step-by-step explanation:
(1/4) ^ (x+1) = 32
Rewriting 32 as 2^5 and 1/4 and 2^-2
2^-2 ^ (x+1) = 2^5
We know that a^b^c = a^ ( b*c)
2 ^ (-2x-2) = 2 ^ 5
Since the bases are the same, the exponents have to be the same
-2x-2 = 5
Add 2 to each side
-2x = 7
Divide by -2
x = -7/2
15. 6 - -3 = 6 + 3 = 9. Answer: 9 degrees C
16. 7 - -7 = 7 + 7 = 14. Answer: 14 degrees F
17. -1 - -5 = -1 + 5 = 4. Answer: 4 degrees C
18. 5 - -2 = 5 + 2 = 7. Answer: 7 degrees C
19. 130 - -110 = 130 + 110 = 240. Answer: 240 degrees C
Answer:
16 millimeters per min
Step-by-step explanation:
divide 720 by 45 and you get 19
If you would like to solve the system of equations, you can do this using the following steps:
x - 3y = 12 ... x = 12 + 3y
2x + 6y = 60
__________
<span>2x + 6y = 60
</span>2 * (12 + 3y) + 6y = 60
24 + 6y + 6y = 60
12y = 60 - 24
12y = 36
y = 36/12
y = 3
<span>x = 12 + 3y = 12 + 3 * 3 = 12 + 9 = 21
</span>
(x, y) = (21, 3)
The correct result would be <span>(21, 3).</span>
