The equation can be modeled as
X + X + (X+4) = 61
X is used for all because they are all the same number and can be given the same variable
The third is given plus four so we can use a common variable
3x + 4 = 61
3x = 57 (subtracted four)
x = 19 (divided by three)
Solving for third side so x + 4
The third side is 23 inches
(3,6)
4x + y > 19
4(3) + 6 > 19
12 + 6 > 19
18 > 19
No
Answer:
Step-by-step explanation:
x + 2y = 8
x - y = 2
x + 2y = 8
-x + y = -2
3y = 6
y = 2
x - 2 = 2
x = 4

Answer:
π³/1296
Step-by-step explanation:
∫ [ (asin x)² dx / √(4 − 4x²) ]
Factoring the denominator:
∫ [ (asin x)² dx / √(4 (1 − x²)) ]
∫ [ (asin x)² dx / (2√(1 − x²)) ]
½ ∫ [ (asin x)² dx / √(1 − x²) ]
If u = asin x, then du = dx / √(1 − x²).
½ ∫ u² du
⅙ u³ + C
Substitute back:
⅙ (asin x)³ + C
Evaluate between x=0 and x=½.
⅙ (asin ½)³ − ⅙ (asin 0)³
⅙ (π/6)³ − ⅙ (0)³
π³/1296
Answer:
75.7
Step-by-step explanation:
Area of the sector,
17²×π×30/360
= 289π/12
= 75.7 (rounded to the nearest tenth)
