Answer: x^2+10x+5x+50 = x^2+15x+50
Step-by-step explanation:
Basically, use something called FOIL. It stands for first, outer, inner, last. Basically multiply the first x, by the first x in the second parenthesis. Then multiply that x by the outer x in the second parenthesis. After that, multiply the 5 by the inner x. Then the five by the ten.
X=amount of apples bought. (in pounds)
y=amount of bananas boutht (in pounds)
We can suggest this system of equations:
x+y=3.8
1.9x+0.75y=5.84
We can solve this system of euqtions by substitution method.
x+y=3.8 ⇒ y=3.8-x
1.9x+0.75(3.8-x)=5.84
1.9x+2.85-0.75x=5.85
1.15x=5.84-2.85
1.15x=2.99
x=2.99/1.15
x=2.6
y=3.8-x
y=3.8-2.6
y=1.2
Answer: C. 2.6 pounds of apples; 1.2 pounds of bananas.
Answer:
The area of the sector is 8*pi cm² or 25.13272 cm².
Step-by-step explanation:
In order to calculate the area of a circular sector we can apply a rule of three in such a way that the circle's area, pi*r² cm², is related to 360º in such a way that "x" cm² is related to the angle of the sector. We have:
pi*r² cm² ---------> 360º
x cm² ------------> 80º
pi*r²/x = 360/80
360*x = 80*pi*r²
x = 80*pi*r²/360
x = 80*pi*(6)²/360
x = 80*pi*36/360
x = 8*pi cm²
The area of the sector is 8*pi cm² or 25.13272 cm².
