Answer:
x= -5 + 5
, x= -5 - 5
Step-by-step explanation:
Since this quadratic is set to zero, we can use the quadratic formula to solve this.
x^2 + 10x - 2400 = 0
Quadractic formula = x= -b +- 
/2a
For this equation:
a= 1, b=10, c=-2400
Plug these numbers into the equation and solve.
x= -10 +- 
)/2(1)
x= -10 +- 
/2
x= -10 +- 
/2
x= -10 +- 
/2
x= -10 +- 5 * 2/2
x= -10 +- 10 / 2
Divide by 2.
x= -5 +- 5
Answer:
x= -5 + 5 or x= -5 - 5
512 root 3 equals 886.810
If by area you mean surface area then the answer is 248 square inches but if you mean volume the answer is 240 cubed inches.
I believe you multiple 343 times a hundred and the answer you gt you divide it by 35 and then you get 980?
Answer:
2 8/11 = b
Step-by-step explanation:
2b + 8 - 5b + 3 = -13 + 8b - 5
combine like terms
11 - 3b = -18 + 8b
add 3b
11 = -18 + 11b
add 18
29 = 11b
divide by 11
2 8/11 = b
