7 0

Answer:

7

Step-by-step explanation:

7.base of triangle=√(32.5²-28²)

=√4.5(32.5+28)

=√4.5(60.5)

=√272.25

=16.5

area of triangle=1/2 ×16.5×28

=231

volume=231×31=7161 km³

8.

39.4-25=14.4

width=√(30.6²-14.4²)

=√16.2(30.6+14.4)

=√16.2(45)

=√729

=27

volume=(25+39.4)/2 ×27×35

=(64.4)/2×27×35

=32.2×27×35

=30429 cm³

Open the picture from the other question and do it here

Alik [6]

$k(x) - g(x) + f(x)$

$(k(x) + f(x)) - g(x)$

$((2x + 5) + (x - 1)) - ( {6x}^{2} - 4x + {3x}^{4}$

$(2x + 5 +x - 1) - 6 {x}^{2} + 4x - {3x}^{4}$

$2x + 5 +x - 1 - 6 {x}^{2} + 4x - {3x}^{4}$

$( - {3x}^{4} ) + ( - {6x}^{2} ) + (2x + x + 4x) + (5 - 1)$

$- {3x}^{4} - {6x}^{2} + 7x + 4$
