Prove the sum of two rational numbers is rational where a, b, c, and d are integers and b and d cannot be zero. Steps Reasons 1.

harkovskaia [24]

Answer:

$\dfrac{ad+bc}{bd}$

Step-by-step explanation:

Let $\frac{a}{b}$ and $\frac{c}{d}$ be two rational numbers, where b and d are not zero and a, b, c and d are integers.

1. Given:

$\dfrac{a}{b}+\dfrac{c}{d}$

2. Multiply to get a common denominator :

$\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{ad}{bd}+\dfrac{cb}{db}$

3. Simplify:

$\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{ad}{bd}+\dfrac{cb}{db}=\dfrac{ad+bc}{bd}$

4. Since $b\neq 0,\ d\neq 0,$ then $bd\neq 0.$

If $a,b,c,d$ are integers, then $bd, ad,bc, ad+bc$ are integers too. So the fraction

$\dfrac{ad+bc}{bd}$

is a rational number

How do you do this question?

max2010maxim [7]

Answer:

∫₁⁵ 2t (t² + t³) dt

Step-by-step explanation:

The area is ∫ₓ₁ˣ² y dx. To parameterize, replace x₁ and x₂ with t₁ and t₂. Replace y = f(x) with y = f(t), and replace dx with (dx/dt) dt.

x = 5 + t², so dx = 2t dt.

∫₁⁵ (t² + t³) (2t dt)

∫₁⁵ 2t (t² + t³) dt

Can someone please help with my math homework? this is so confusing.

Hi there friend, your answer for perimeter is 18.

I’ve included a graph below to help explain why but basically if you count the squares, each side measures 4 1/2 units so if you multiply 4 1/2 units by 4(the number of sides) you get 18.
