x = 1.56 or x = -2.56
Step-by-step explanation:
From the equation;
x2 +x − 4 = 0
a = 1 , b = 1, and c = -4
x = (-b ± √(b² -4ac))/2a
= (-1 ± √(1²- 4×1×-4))/2
= ( -1 ± √(17)/2
= (-1 ± 4.12)/2
= (-1 + 4.12)/2 or (-1 - 4.12)/2
the answer is: the length is 5/6 yards.
give me a or a 5 star rating if this is correct!
step-by-step explanation:
2/3x + 7 = 29
two thirds = 2/3
plus a number = x
at least 29 = 29
there for you should get 2/3x + 7 = 29
