Answer:
Step-by-step explanation:
false check the equality
Answer:
AC = 2x - 13 Cm
BC = 3x + 4 Cm
AB = 36 Cm
AB = AC + BC
BC = AB - AC
= 36 - (2x - 13)
= 36 - 2x + 13
= 49 - 2x
but, BC = 3x + 4
so equating both the equation we get
3x + 4 = 49 - 2x
3x + 2x = 49 + 4
5x = 53
x = 53/5
x = 10.6
BC = 49- 10.6*2
= 49- 21.2
= 27.8 CM
Answer:
-39x^2 + 17x
Step-by-step explanation:
= 5x - 60x^2 + 3 (4x+7x^2)
= 5x - 60x^2 + 12x + 21x^2
= -39x^2 + 17x
Answer:
The answer should be B: 33.0
Step-by-step explanation:
I just used a calculator.
I'm not sure what you mean by this, but if you mean rounding, I got an answer.
Say you're rounding 24 to 30.
24 is closer to 20 than 30.
But if you were rounding 25 to 30, 25 would be closer to 30, not 20.
I guess it's kind of confusing.
