remove the ( ) fast and then add the numbers that look the same.
(22+19b)+7
22+19b+7
22+7+19b
= 29+19b
18+(5+6m)
18+5+6m
= 23+6m
here u don't care about same or not same u just multiply or divide
11s(4)
= 44s
10y(7)
= 70y
(9+31+5)(7times5)times4)
(45)(35)4
(1575)4
= 6300
Answer: what wrong
Step-by-step explanation:
A polar coordinate is that which can be written as (r, θ) where r is the radius and θ is the angle.
The radius, r, is also the hypotenuse of the right triangle that can be formed. Hence, it can be calculated through the equation,
r² = x² + y²
If we are to simplify this for the r alone, we have,
r = sqrt (x² + y²)
Substituting the known values,
r = sqrt ((4)² + (-4)²) = 4√2
The x and y can be related through the trigonometric function, tangent.
tan θ = y/x
To solve for θ
θ = tan⁻¹(y/x) = tan⁻¹(-4/4) = -45° = 315°
Hence, the polar coordinate is <em>(4√2, 315°)</em>
10.4375
12.875×2=25.75 46.625-25.75=20.875 20.875÷2=10.4375
