Answers

Answer:

Answer to the first part:  8a³b + 4ab

Step-by-step explanation:

Perimeter = distance around the three sides

P = 6a³b + 2a³b + 4ab

P = (6a³b + 2a³b) + 4ab           add like terms

P = 8a³b +4ab                          Simply

The value of the perimeter and area of the triangle are,

20.52 cm²  and 28.68 cm

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Now, By Using Pythagoras theorem to find the base of the triangle as;

a² = 6² - 3²

a ² =  27

a = √27

And, b² = 9² - 3²

b² =  72

b = √72

Hence, Base = √27 + √72

= 13.68

So, We get;

Area = 0.5 x 13.68 x 3

Area = 20.52 cm²  

And, The value of perimeter is,

Perimeter = 9 + 6 + 13.68

= 28.68

Thus, The value of the perimeter and area of the triangle are,

20.52 cm²  and 28.68 cm

PLEASE HELP WITH THIS ONE QUESTION
A 60 cm by 80 cm photo is to be surrounded with a matting of equal width. The photo and matting is to be covered by a 1 m^2 sheet of expensive glass. Find the width of the matting.

Answers

We know the area = width height. So we can set up this equation, where x is the unknown space between the entire frame and the photo:
(60cm + x) (80cm + x) = 1m^2

And then convert the m^2 to cm^2 so it’s all the same units:
1m^2 = 1m x 1m = 100cm x 100cm = 10000cm^2

So we get:
(60cm + x) (80cm + x) = 10000cm^2

Then solve for x:

(60cm + x) (80cm + x) = 10000cm^2
4800 + 140x + x^2 = 10000
x^2 + 140x - 5200 = 0

Using the quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / 2a

x = ( -140 +/- sqrt(140^2 - 4(1)(-5200)) )/ 2(1)
x = ( -140 +/- sqrt(19600 -(-20800)) )/ 2
x = ( -140 +/- sqrt(40400)) / 2

x = ( -140 + 200.9975 )/ 2
x = 30.49875

x = (140 - 200.9975)/2
x = -60.9975

So we get:
x = 30.49875 or -60.9975


The width of the matting is the part of the width underneath the photo (60cm) plus the spacing between the photo and the border, x (which would have to be 30.5 because it doesn’t make sense as a negative). So it’s:
60cm+30.50cm = 90.50 cm

The width of the matting is 90.50cm.

Step-by-step explanation:

You have the relation ...

  (left side number) × (top number) = (number in the area box)

This means ...

  (top number) = (number in the area box)/(left side number)

  top number = 680/17 = 40 . . . number in the quotient box

and ...

  17 × 8 = number in the area box = 136

__

The number in the right-side box is the remainder, the difference between the dividend 820 and the sum of the numbers in the other two area boxes.

  820 -680 -136 = 4 . . . . number in the right-side box

-7x^11 is the answer.

One way that personally helps me remember the exponents properties is to imagine it written out with multiplication:

x^4 is the same as
x*x*x*x

And raised to 2 is the times itself a total of 2 times
(x*x*x*x) (x*x*x*x)

For a total of x^8. Or in other words, we can say we can “distribute” the double exponents.

x^8 times x^3 is

(x*x*x*x*x*x*x*x) * (x*x*x)
There are a total of 11 x’s or x^11

Another property when exponents are multiplied together is that they are added.

so
x^8 * -7 * x
is the same as

x^8 * x^3 * -7

And the answer is

x^11 * -7 =

-7x^11
