Answer:
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
<u>x = 1.56 or x = -2.56</u>
Answer:
= $2,541.5
Step-by-step explanation:
I = P * T * R/100
I = 2300*7 * 1.5/100
I = $241.5
Total amount in the account will be $2300 + $241.5
= $2,541.5
9/2 mph. You would need to multiply both by six to get exact mph, and three fourths times six is 18/4=9/2=4.5 mph
68 sq in. You multiply 5 by 12 ( amount of inches in a foot) and get 60, then add the extra eight inches(these inches are from 5.8). Hope this helps :)
