Answer:
42x-24y-5
Step-by-step explanation:
We can start by using the distributive property.
This will help us rewrite the expression, since the terms in the parentheses can't be combined.
I'll attach an image to better explain this.
When using it, we'll get:
6*7x+6*-4y-5
Simplify.
42x-24y-5
This is our final answer since there are no like terms that can be combined.
So, if z = x+iy,
|z| = \(\sqrt{x^2+y^2}\)
and \( |z|^2 = x^2 + y^2 \)
so if x = 3+bi
|x|^2 = 3^2 + b^2
which is given to be 13
3^2 + b^2 = 13
9+b^2 = 13
b^2 = 13-9
b^2 = 4
b = +\sqrt 4 , -sqrt 4
b = +2,-2
Hence, the possible values of b are +2 or -2.
Answer:
The area is 49.5 cm^2
Step-by-step explanation:
To find the area of the sector, we are going to use the formula for the area of a sector
Mathematically, we have this as;
A = theta/360 * pi * r^2
r = 9 cm and theta = 70
Substituting these values
A = 70/360 * 3.142 * 9^2
A = 49.5 cm^2
Answer:
$1
Step-by-step explanation:
$20 - $16 = $4, So Josh's total was $4.
$4 divided by 4 books is $1 each.
