Answer:
(x + y)² = 25
Step-by-step explanation:
The expansion of (x + y)² is
(x + y)² = x² + y² + 2xy ← substitute x² + y² = 15 and xy = 5
= 15 + 2(5)
= 15 + 10
= 25
I should say that 13, 24, 14 are the next three numbers, because as you can see above the first(11) number is the third(12) number minus 1 and the fourth(23) is the second (22) plus 1 if you understand what I`m trying to say
Area of the 2 right triangles =2 (1/2 x 1.5 x 2 ) = 3 in²
Area of the 3 rectangles = (1.5 + 2 + 2.5) x 11 = 66 in²
Total Surface area = 3 + 66 = 69 in²
Answer: 69 in²
X*2 +5 =41
Subtract 5 from both sides
X*2=36
Square root of 36 is 6
X=6
Solve
6*2+5 =41
This’s correct!
The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.
So, if the input is 15.4, the output will be
