Answer:

d. \:  \:  \: 25 {x}^{6}

Step-by-step explanation:

Given,

Side of the square

= 5 {x}^{3}

Therefore, area of the square = side × side

=  {5x}^{3}  \times 5 {x}^{3}

= 5 \times 5 \times  {x}^{3 + 3}

= 25 {x}^{6}

The formula for calculating the area of a square is A=a^2. (a=side)
There are multiple ways to solve this but I’m gonna use the simple way to explain.
All we have to do here is take the side times the side:
5x^3•5x^3
5•5=25
**Careful** exponents are added, not multiplied.
25x^6 is the answer

(-3) + 8 – 7x7<br> I need help with this on
nika2105 [10]

Answer: -44

Step-by-step explanation: PEMDAS(Parenthesis; Exponent; Multiply; Divide; Add; Subtract)

First you multiply the seven with the other seven to get 49. The problem will look like this: (-3) + 8 - 49. Now just add the -3 and 8. You'd get 5.

Now the problem looks like this: 5 - 49. And you then get -44.

X<br> 50<br> 50<br> X =<br> degrees<br><br> Please help with this problem I am going crazy
sveta [45]

Answer:

x=80°

Step-by-step explanation:

Triangles always add up to 180°.

As you have 2 angles, you would have to add them together and then take it away from 180° to get your answer.

50+50=100°

180-100=80°

Hope this helps :)

A retangle has an area of 30 square meters and a perimeter of 34 meters what are the dimensions of the retangle
s344n2d4d5 [400]

Answer: Length = 15 meters

Width = 2 meters

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

Area of a rectangle = l × w

where l = length

w = width

Therefore,

2l + 2w = 34 ...... i

l × w = 30 ........ ii

From equation i

2l + 2w = 34

Divide through by 2.

l + w = 17 ...... iii

Then, l = 17 - w ........ iv

Put equation iv into ii

l × w = 30

(17 - w) × w = 30

17w - w² = 30

w² - 17w + 30 = 0

w² - 15w - 2w + 30 = 0

w(w - 15) - 2(w - 15) = 0

(w - 2) = 0

w = 0 + 2 = 2

w - 15 = 0

w = 0 + 15 = 15

Length = 15 meters

Width = 2 meters
