A garden has an area of 286ft. It’s length is 9ft more than it’s width. What are the dimensions of the garden?
Gelneren [198K]

Answer:

13

Step-by-step explanation:

  • x × (x + 9) = x² + 9x = 286
  • x² + 9x - 286 = 0
  • (x - 13)(x + 22)
  • x = 13 or -22
  • Since you cannot have negative length, it’s 13

Natali [406]
<span><u><em>The correct answer is: </em></u>
green and blue.

<u><em>Explanation</em></u><span><u><em>: </em></u>
We want to see which fractions </span></span>\frac{3}{4} is a multiple of. We know that \frac{3}{4} is a multiple of \frac{1}{4}, because \frac{1}{4}*3=\frac{3}{4}.

We can divide fractions to determine if \frac{3}{4} is a multiple of \frac{1}{2}:
\frac{ \frac{3}{4}}{ \frac{1}{2}};

in order to divide fractions, flip the second one and multiply:
\frac{3}{4})*\frac{2}{1}=\frac{6}{4}=1 \frac{1}{2}.
This did not divide evenly, so \frac{3}{4} is not a multiple of 1/2.

Checking to see if \frac{3}{4} is a multiple of \frac{1}{8}, \frac{ \frac{3}{4}}{ \frac{1}{8}};

flip the second one and multiply:
\frac{3}{4}*\frac{8}{1}=\frac{24}{4}=6.
This divided evenly, so \frac{3}{4} is a multiple of \frac{1}{8}.

If anyone can tell me how to do 26 that would be great PLEASE SHOW WORK
katovenus [111]

Hello from MrBillDoesMath!

Answer:

Discussion:

I stared at the numbers 19, 29, 39, 49, 59, 69,... for a second and noticed that adding 10 to any number gives the next number to the right. For example,


19 + 10 = 29

29 + 10 = 39

39 + 10 = 49

etc.....


A recursive formula would be:

a(0) = 19        

a(n+1) = a(n) + 10    if n >= 0

c

Step-by-step explanation:

x²+y²+4x+6y=0

compare with x²+y²+2gx+2fy+c=0

centre is (-g,-f)=(-2,-3)

radius=√(g²+f²-c)=√((-2)²+(-3)²-0)=√13

23j-21g+20e-13+52e-37j+45-49e<br> (Like terms)
eduard

The solution to the algebraic expression is: 23e - 21g - 14j + 32

What are algebraic expressions?

Algebraic expressions are mathematical expressions that contain variables, coefficients, and arithmetic operations such as addition, subtraction, division, and multiplication.

Solving algebraic expressions are an important part of mathematics as it helps to improve the aptitude and solving skills of the students.

From the given information, we have;

23j - 21g + 20e - 13 + 52e - 37j + 45 - 49e

let's rearrange by taking the like terms to the same sides;

= 23j -37j - 21g + 20e + 52e - 49e - 13 + 45

= -14j - 21g + 23e + 32

= 23e - 21g - 14j + 32

Therefore, we can conclude that the solution to the algebraic expression is: 23e - 21g - 14j + 32
