Find the equivalent fraction to next expression 3b^2 + 2(a+5.4b) -2.4b + 1.5a - 2b^2 a 2b2 + 3.5a + 8.4 b b b2 +3.5a + 8.4b c 2b

Neporo4naja [7]

Answer:

b²+3.5a+8.4b

Step-by-step explanation:

Given the expression

3b^2 + 2(a+5.4b) -2.4b + 1.5a - 2b^2

Expand

3b^2 + 2a+10.8b -2.4b + 1.5a - 2b^2

Collect the like terms

= 3b²-2b²+2a+1.5a+10.8b-2.4b

= b²+3.5a+8.4b

Hence the equivalent expression is b²+3.5a+8.4b

If the ratio of the triangular pyramids' surface areas is 4:9, what is F?

VladimirAG [237]

Answer:

The answer to your question is f = 10.35 in

Step-by-step explanation:

Data

Proportion = 4:9

height 1 = 4.6 in

height 2 = f

Process

1.- Write the proportion

$\frac{4}{4.5} = \frac{9}{f}$

2.- Solve for f

$f(\frac{4}{4.6}) = f(\frac{9}{f})$

$f(\frac{4}{4.6}) = 9$

$4.6\frac{4f}{4.6} = 9(4.6)$

4f = 41.4

$\frac{4f}{4} = \frac{41.4}{4}$

f = 10.35 in
