Answer:

\text{Area}=\frac{15(x+1)}{2(x-2)}

Step-by-step explanation:

Length of the rectangle given in the picture = \frac{5x+5}{x+3}

Width of the rectangle = \frac{3x+9}{2x-4}

Area of the rectangle = Length × Width

                                    = \frac{5x+5}{x+3}\times \frac{3x+9}{2x-4}

                                    = \frac{5(x+1)}{x+3}\times \frac{3(x+3)}{2(x-2)}

                                    = \frac{15(x+1)(x+3)}{2(x+3)(x-2)}

                                    = \frac{15(x+1)}{2(x-2)}

Therefore, area of the given rectangle is \frac{15(x+1)}{2(x-2)}.

Simplify :<br><br> -0.5(0.8 + 8y)
Minchanka [31]

Answer:

-0.4-4y

Step-by-step explanation:

-0.5(0.8+8y)

Distribute -0.5 into the parentheses

= -0.5×0.8+(-0.5)×8y

= -0.4+(-4y)

A negative and a positive make a negative

= -0.4-4y

I hope this helps!

Determine coefficients a and b such that p(x)=x2 ax b satisfies p(1)=5 and p′(1)=11.
Murrr4er [49]
p(x)=x^2+ax+b
p'(x)=2x+a

Given that p'(1)=11, you have

p'(1)=2+a=11\implies a=9

and given that p(1)=5, you have

p(1)=1+9+b=5\implies b=-5

So you get

p(x)=x^2+9x-5

Which equation shows one way to find the value of 45 × 4? 45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ? 45 × 4 =
erma4kov [3.2K]

Answer:

45 × 4 = (9 × 5) × (2 × 2) = (9 × 2) × (5 × 2) = 18 × 10 = ?

Step-by-step explanation:

Which equation shows one way to find the value of 45 × 4?

45 × 4

Splitting each number into factors of each other

45 = 9 × 5

4 = 2 × 2

45 × 4 = (9 × 5) × (2 × 2)

45 × 4 = (9 × 2) × (5 × 2)

45 × 4 = 18 × 10

Option A is the correct option
