Area of triangle is 1/2 * base * height
1/2 * (2+2+2) * 4
1/2 * 6 * 4
12 cm^2
Area of rectangle is length * breadth
5 * 2
10 cm^2
Total area is 10 + 12
That is 22 cm^2.

To find the area, do 2+2+2+4+5
To find the volume, do 2×2×2×4×5

How to solve 6x - 9 - 2 (1 - x) = x + 9

Likurg_2 [28]

$x = 2.857$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}$

$6x - 9 - 2(1 - x) = x + 9 \\ ⇢ 6x - 9 - 2 + 2x = x + 9 \\ ⇢ 8x - x = 9 + 11 \\ ⇢ 7x = 20 \\ ⇢ x = \frac{20}{7} \\ ⇢ x = 2.857$

${ \bf{ \underbrace{To\:verify:}}}$

$6 \times 2.857 - 9 - 2(1 - 2.857) = 2.857 + 9 \\ ➪ \: 17.142 - 9 - 2 \times( - 1.857) = 11.857 \\➪ \: 8.142 + 3.714 = 11.857 \\➪ \: 11.856 = 11.857 \\ ➪ \: 11.86 = 11.86 \\ ➪ L.H.S.=R. H. S$

Hence verified.

Can someone solve for x please:

Alecsey [184]

THe LCD is x(x^2 - 4)

so multiplying through by this we get:-

2x(x + 2) + 7x = 5(x^2 - 4)
2x^2 + 4x + 7x = 5x^2 - 20
3x^2 - 11x - 20 = 0

(3x + 4)(x - 5 ) = 0

so x = 5 , -4/3

Its the second choice
