area = (l)(w)(h)
24 = 4(3 + b)
24 = 12 + 4b
-12 on both sides
12 = 4b
/4 on both sides
b = 3 inches
Substitute b = 3 inches in width
3 + b
3 + 3 = 6 inches
Answer:
width = 6 inches
Answer:
No real solutions
Step-by-step explanation:
Use the discriminant formula, D = b² - 4ac
D = b² - 4ac
Plug in b, a, and c:
D = b² - 4ac
D = (8)² - 4(1)(20)
D = 64 - 80
D = -16
Since the discriminant is negative, there are no real solutions
Answer:
26
Step-by-step explanation:
Average = all the numbers added together then divided by the amount of numbers in the equation
21+24+25+25+26+26+26+26+27+29= 255
Since there are ten numbers in this equation, divide the sum by 10
25.5
round up
26
Answer:
13
Step-by-step explanation:
f(-3)=2(-3)-5(-3)+4. = -6+15+4= 13. f(a)=13
