The rainfall total two years ago was 10.2 inches. Last year's total was 20% greater. What was last year's rainfall total?

Answers

Answer 1

Answer: basically, to answer this question, you have to increase 10.2 by 20%.hence,

10.2×20= 204
204÷100= 2.04
10.2+2.04= 12.24
answer- 12.24inches

Answer 2

Answer: 10.2+10.2*20/100= 12.24 inches

Answer:

$(2b-x)(7x^2-2)$

Step-by-step explanation:

We have to factor the expression $14bx^2-7x^3-4b+2x$

We apply the method of grouping to factor it.

Make groups

$(14bx^2-7x^3)+(-4b+2x)$

Take GCF

$7x^2(2b-x)-2(2b+x)$

Finally, factored out the common factor

$(2b-x)(7x^2-2)$

The factored form of the given expression is

$(2b-x)(7x^2-2)$

hello,

14bx²-7x^3-4b+2x= -7x^3+14bx²+2x-4b
=-7x²(x-2)+2(x-2b)
=(x-2b)(-7x²+2)
=(2b-x)(7x²-2)

$(6c - 3)/(3c^(2) - 12) = (3(2c) - 3(1))/(3(c^(2)) - 3(4)) = (3(2c - 1))/(3(c^(2) - 4)) = (2c - 1)/(c^(2) - 4) = (2c - 1)/(c^(2) + 2c - 2c - 4) = (2c - 1)/(c(c) + c(2) - 2(c) - 2(2)) = (2c - 1)/(c(c + 2) - 2(c + 2)) = (2c - 1)/((c - 2)(c + 2))$
