If x (x+y) = 27 and y (x+y) = 54, what is the value of (x+y)^2?
Answer:
9x^2
Step-by-step explanation:
It is given that:
x ( x + y ) = 27
If one manipulates the equation, by dividing by x, they get:
x + y = 27/x
It is also given that:
y ( x + y ) = 54
Again, manipulate the equation, only this time, divide by y,
x + y = 54/y
It is obvious that;
x + y = x + y
Yet this was proven;
x + y = 27/x
x + y = 54/y
Therefore, the following has to be true;
27/x = 54/y
To sove the proportion, use cross products;
27/x = 54/y
54x = 27y
Inverse operations:
54x = 27y
/27 /27
y = 2x
Substitute;
(x + y)
y = 2x
= (x + 2x)
= 3x
Now solve:
(3x)^2
9x^2

Pls help me out, I need to know what value of x makes this equation true
equation: 6(2x – 11) + 15 = 3x + 12
I have already found the answer to this equation (x = 7) but I need to know what value of x makes the equation true.
(If it's 7, my brain just needs a break from stuff, I've been up since 4 in the morning)
Answer:
x = 7
Step-by-step explanation:
12x - 66 + 15 = 3x +12
12x - 51 = 3x + 12
9x = 63
x = 7

A − ¾ × (-2/17)
B− ¾ × 8 ½
C ¾ × 17/2
D ¾ × (−8 ½ )
brainliest answer . Help please answer and pls don't answer if you don't understand .
Answer:
1/2
Step-by-step explanation:
We do change in y over change in x
Formula for Rate of Change on Slope
y2-y1/x2-x1
For Y
We use coordinate (-2, -4)
-4--2
= -2 - -4
= 2
For X
We use coordinate (0, -4)
0 -- 4
= 0 + 4
= 4
Now we put y over x to find the rate of change in slope
2/4, simplified would be 1/2

5- 3/14= ?
Answer:
4 11/14
Step-by-step explanation:
Follow PEMDAS order of operations ( Since its only 1 equation just do what the equation is asking you to do which is subtract)
5-3/14 = 5/1 - 3/14 = 70/14 - 3/14
= 67/14

A circle has a diameter of 20 ft. What is the diameter? *
Since the question provided the diameter instead of radius, the diameter is 20 feet
Answer: well the diameter would be 20ft. If you meant to ask for the circumference then its 62.857ft
Step-by-step explanation:
Diameter of a circle is 20 feet.
Hence it's Radius = 20/2 = 10 ft
We know circumference = 2πr
Circumference = 2 × 22/7 × 10 ft
Circumference = 44 × 10/7= 440/7
Circumference = 62.857 ft
