5 times marys age is the same as 28 less than 7 times her age. Find her age

Gnom [1K]

setup a simple algebraic equation and solve.

5x = 7x-28

-5x -5x

0=2x-28

+28 +28

28=2x

Now divide both sides by 2 and you get that she is 14

Multiply (3x2-4x+5)(x2-3x+2)

Iteru [2.4K]

So with this, you can rewrite the equation as: $(3x^2\times x^2)+(3x^2\times -3x)+(3x^2\times 2)+(-4x\times x^2)+(-4x\times -3x)+(-4x\times 2)+(5\times x^2)+(5\times -3x)+(5\times 2)$

Firstly, solve the multiplication: $3x^4+(-9x^3)+6x^2+(-4x^3)+12x^2+(-8x)+5x^2+(-15x)+10$

Next, combine like terms, and <u>your answer will be: $3x^4-13x^3+23x^2-23x+10$ </u>
