Answer:
x = (-5 ± 2√10) / 3
Step-by-step explanation:
5 − 10x − 3x² = 0
Write in standard form:
-3x² − 10x + 5 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)
x = [ 10 ± √(100 + 60) ] / -6
x = (10 ± 4√10) / -6
x = (-5 ± 2√10) / 3
The answer is: 3 3/8 sq ft so C
5 times 2 times 8 would equal 80
Answer :80
Answer:
4.3
Step-by-step explanation:
what you wanna do is add the 1.5 and the -2.8 together, then devide it by 0.4 four, and thats what X equals.
