Answer:
swimmer b swims 100 yards. approximately how many more feet did swimmer a swim than swimmer b? 2.
Step-by-step explanation:
The teacher would have to grade 322 problems
14 (problems) x 23 (students)
Answer: 322
Yes, you made an algebraic error. By multiplying 18 x 4, you messed up on order of operations.
(x+9)(x+2)*4
becomes:
(x^2+11x+18)*4
= 4x^2 + 44x + 72
anyway, this is how I would do this problem:
(x+9)(x+2)(4) = 912
(x+9)(x+2) = 228
x^2 + 11x + 18 = 228
x^2 + 11x - 220 = 0
(x+21)(x-10) = 0
x = -21 or 10
The dimensions can't be negative, so we only use x = 10
The dimensions are then 10+9, 10+2, 4
or 19, 12, 4
1) Now,
a + 27° = 90° (right angle triangle)
◆ a = 63°
2) Now,
b + b + b = 90° (right angle triangle)
or, 3b = 90°
◆ b = 30°
3) Now,
c + c + 40° = 90° (right angle triangle)
or, 2c = 90° - 40°
or, c = 50°/2
◆ c = 25°
4) Here,
◆ e = 41° (vertically opposite angle)
◆ f = 82° ( vertically opposite angle)
Now,
d + e + f = 180° (straight angle)
or, d + 41° + 82° = 180°
or, d = 180° - 123°
◆ d = 57°
Then,
◆ g = d = 57° (vertically opposite angle)
It is all correct answer...
I hope u understand...
Thank you ♥♥ my cutie...
