The answer is 20 feet by 20 feet. Let's solve the equation: (x – 8)^2 = 144. (x - 8)^2 = 12^2. Since a^2 = b^2 is the same as a = b, then (x - 8)^2 = 12^2 can be simplified to: x - 8 = 12. Now, solve for x. x = 8 + 12. x = 20. Therefore, the dimensions of the original lawn were 20 feet by 20 feet.

To write the polynomial 3x3 + x2 − 8x5 + 2x3 − 4x in standard form, which terms should be combined? A. 3x3 and 2x3 B. 3x3, 2x3,

djyliett [7]

Answer:

Option A. is correct

Step-by-step explanation:

Like terms are those terms that have same variables of same powers. Terms that are not like terms are said to be unlike terms.

For example $2x^3,7x^3$ are like terms and $5x^2,9x^5$ are unlike terms.

Given polynomial is $3x^3+x^2-8x^5+2x^3-4x$

Like terms need to be combined to write the polynomial in standard form

Here, like terms are $3x^3,2x^3$

Option A. is correct.

A train travels from New York City to Washington D.C. and then back again. The table below shows the number of Coach tickets sol

alisha [4.7K]

Answer: $74

Step-by-step explanation:

Let C represent the cost of a coach ticket

Let B represent the cost of a business ticket

Washington: 150C + 50B = 18,450

NY City: 170C + 100B = 27,280

Solve the system using the Elimination method:

-2(150C + 50B = 18,450) → -300C - 100B = -36,900

1(170C + 100B = 27,280) → 170C + 100B = 27,280

-130C = - 9,620

÷ -130 ÷ -130

C = 74

Scilla [17]

Area of a square =a^2
40000=a^2
a=200 inch

Now if u can imagine a square shape with side of 200 inch each.it makes right angles
so use pythagorean theorm

c^2=a^2+b^2
c^2=(200)^2+(200)^2
c=282.84 inch

ength of a fence is 282.84 inch
