Answer:
30÷5=6.
Step-by-step explanation:
Quotient means to divide, 30÷5 is 6 since 5x6 or 6x5 is 30.
2800 + 1.18x = y
x = monthly sales
y = monthly income
y needs to be at least 6400 so that means;
2800 + 1.18x ≥ 6400
1.18x ≥ 6400 - 2800
x ≥ (6400 -2800) / 1.18
x ≥ 3050
So she needs to earn at least 3050, which means <span>≥ 3050</span>
(3x^2 - 2x + 12) + (x^2 + 8x -2)
= (4x^2+6x+10)(2x^2)
= 4x^2(2x^2)+6x(2x^2)+10(2x^2)
= 8x^4 + 12x^3 + 20x^2
Answer:
1. In the multiplication of the imaginary parts, the student forgot to square of i. OR
2. The student has only multiplied the real parts and the imaginary parts.
Correct value
.
Step-by-step explanation:
The given expression is

A student multiplies (4+5i) (3-2i) incorrectly and obtains 12-10i.
Student's mistake can be either 1 or second:
1. In the multiplication of the imaginary parts, the student forgot to square of i.
2. The student has only multiplied the real parts and the imaginary parts.

Which is not correct. The correct steps are shown below.
Using distributive property, we get



![[\because i^2=-1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20i%5E2%3D-1%5D)


Therefore, the correct value of
is
.
You could change 0.393 to a fraction by putting it over 1000
in this case put it over 0.393= 396/1000
the / is the fraction
it is 396 over 1000
