Answer:
x < -20
Step-by-step explanation:
x / -4 + 14 >20
Subtract 14 from each side
x / -4 +14-14 > 20 -14
x / -4 > 6
Multiply each side by -4, remembering to flip the inequality
x / -4 * -4 < 6 * -4
x < -20
Answer:
52.4 cm
Step-by-step explanation:
Circumference of a circle = 2πr
Radius, r = diameter / 2
= 17 cm / 2
= 8.5 cm
π = 3.14
Circumference of a circle = 2πr
= 2 × 3.14 × 8.5
= 53.38 cm
Approximately 52.4 cm
Answer:
V = 408 cm cubed
SA = 558 cm squared
Step-by-step explanation:
To find the volume of a prism, multiply the area of the base by the height. This is 1/2 times width times height times length.
V =1/2 l*w*h =1/2* 6*8*17 = 408
To find the surface area of a prism, find the area of the triangular base and the area of each rectangular side.
Area of the base is A = 1/2 * b*h = 1/2 * 6 * 8 = 24. Since there are 2 bases, the area is 48.
Area of the rectangular side is A = b*h = 17*10 = 170. Since there are three, the area is 3*170 = 510.
The surface area of the prism is 48 + 510 = 558.
It would be x=-4 have a good day
