Answer:
2x + y
Step-by-step explanation:
x² + xy - y² = 4
→ Remember the rule, bring the power down then minus 1
2x + y
Answer:
Length is 20 meters and Width is 16 meters
Step-by-step explanation:
A parallelogram is a 4-sided figure with 2 pair of parallel sides.
The perimeter is the sum of all 4 sides of the parallelogram.
Let the length of parallelogram be x and width be y.
The perimeter is 72, thus we can write:
x + x + y + y = 72
or
2x + 2y = 72
Also, width is 4 less than length, thus we can write:
y = x - 4
Now, we replace the 1st equation with the 2nd equation and solve for x first. Shown below:
2x + 2y = 72
2x + 2(x - 4) = 72
2x + 2x - 8 = 72
4x = 72 + 8
4x = 80
x = 80/4 = 20
And now y:
y = x - 4
y = 20 - 4
y = 16
Thus, the Length is 20 meters and Width is 16 meters
41/50%=82
28800-82= 28718.
That may be the answer.
Answer:
28:u multiply something 3 times therefore it is 1/3
29: because the numbers are unknown
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given p + 1 = 2
→ 1 = 2 - p
The above equation is quadratic in p.
p = [ -(-1) ± 
] ÷ 2
p = [1 ± 
] ÷ 2
