Answer:
x=3
y=5
Step-by-step explanation:
x+5y=28 (i)
-x-2y=-13. (ii)
add equation 2 from equation 1
x+5y=28
-x-2y=-13
3y=15
y=5
put the value of y in equation 1
x+5y=28
x+5*5=28
x+25=28
x=28-25
x=3
Answer:
x=28.93(rounded) x=28.929(not rounded)
Step-by-step explanation:
Answer:
Area of the garden = 98 + 19.25 = 117.25 ft²
Step-by-step explanation:
Area of the garden = area of the rectangle + area of the semi-circle
Area of the rectangle = L x B = 14 x 7 = 98 ft²
Area of the semi-circle = 1/2 x πR² = 1/2 x 22/7 x 3.5² = 19.25 ft²
Hence area of the garden = 98 + 19.25 = 117.25 ft²
Answer:
Step-by-step explanation:
f(x) = 2x^3 - 4x.....find f(-2).....so sub in -2 for x
f(-2) = 2(-2^3) - 4(-2)
f(-2) = 2(-8) + 8
f(-2) = -16 + 8
f(-2) = -8 <==
