Answer:
-15c + 2
Step-by-step explanation:
you start by multiplying the coefficients of the parentheses to the numbers inside which gives you
- c - 32c + 5 + 18c - 3
then you simply just group together the like numbers. all "c" 's go together and everything without a "c" goes together
- 1c - 32c + 18c= -15c
5 - 3 = 2
the final answer simplified is
-15c + 2
the picture in the attached figure
we know that
area of the triangle is equal to

in this problem
A=47 in²
b=x
h=x
so

therefore
the answer is
x=9.7 in
Answer: 8.175
Explanation: 8 is the whole number so set that aside look at 7/40, using simple division solve for a decimal
4 is the answer to this question
Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23
