b. Write an equation in standard form representing the area of the picture and the frame. Explain how you arrive at your osition.

Answers

Answer: a) Quadratic equation b) $4x^2+36x+80$

Step-by-step explanation:

Since we have given that

Length of photograph = 8 inches

Width of photograph = 10 inches

It is surrounded by a frame with uniform width 'x'.

So, Length of picture and frame becomes

$x+8+x=2x+8$

Width of picture and frame becomes

$x+10+x=2x+10$

So, Area of picture and frame becomes

$Length* breadth\n\n=(2x+8)(2x+10)\n\n=2x(2x+10)+8(2x+10)\n\n=4x^2+20x+16x+80\n\n=4x^2+36x+80$

Hence, a) Quadratic equation b) $4x^2+36x+80$

in plain and short, "the range of the original is the domain of the inverse and the domain of the original is the range of the inverse".

or just to put it plainly, the inverse is the same set, but backward pairs

$\bf %f(x) = {(8, 3), (4, 1), (0, –1), (–4, –3)}f(x) = \{(8, 3), (4, 1), (0, -1), (-4, -3)\} \n\n\n\stackrel{inv erse}{\{(3, 8), (1, 4), (-1, 0), (-3, -4)\}}$

A parallelogram has a base of 16 inches and a height of 11.7 inches. What is the area of the parallelogram?

Answers

Answer:

A = 187.2 inches²

Step-by-step explanation:

the area (A) of a parallelogram is calculated as

A = base × height

substitute base = 16 inches and height = 11.7 inches into the formula for A

A = 16 × 11.7 = 187.2 inches²

brainly?:)

Step-by-step explanation:

30 is not divisible by 4. The answer is false

Write x^2 − 8x + 13 = 0 in the form (x − a)^2 = b, where a and b are integers.(x − 4)^2 = 3
(x − 3)^2 = 2
(x − 2)^2 = 1
(x − 1)^2 = 4

Can anyone show the steps on how to get the answer?

Answers

Sure.
The answer is (x-4)^2 = 3

Procedure

Complete a perfect square trinomial to factor:

x^2 - 8x + 13 = 0

Notice that -8x = 2(x)(4)

Given tha x is the square root of x^2, we want to include the square of 4, which is 16.

We must just add 16 to the first two terms, which, of course, obliges to substract the same number to maintain the equality. This way:

(x^2 - 8x + 16) + -16 + 13= 0

Now the three terms in parenthesis can be factor as a binomial squared:

(x - 4)^2 + 13 -16 =0

(x - 4)^2 - 3 = 0

(x - 4)^2 = 3 Which is the answer.

Let me know whether you could follow the explanation.
