Answer:
x = 486956.5217
Step-by-step explanation:
5.75% of x = 28000
Of means multiply
Change the percent to a decimal
.0575 * x = 28000
Divide by .0575 on each side
.0575/.0575 * x = 28000/.0575
x = 486956.5217
A) 3(a - b) = 3*a +3*-b = 3a - 3b EQUAL
b) 2a(2 + b) = 4a + 2ab NOT EQUAL
Hello :
the discriminat of each quadratic equation : ax²+bx+c=0 ....(a <span>≠ 0) is :
</span><span>Δ = b² -4ac
1 ) </span>Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ <span>< 0 : no reals solutions</span>
