Joe is building a post for his mailbox. To find the correct dimensions, he needs to expand this expression: (x-3) (x-9) (x-4) Se

kolbaska11 [484]

Answer:

$(x-3)(x-9)(x-4)=x^3-16x^2+75x-108$

Step-by-step explanation:

Given:

The expression to expand is given as:

$(x-3)(x-9)(x-4)$

Let us expand the first two binomials of the given expression using FOIL method.

The FOIL method states that:

$(a + b)(c + d) = ac + ad + bc + bd$

$(x-3)(x-9)=(x\times x)+(x\times -9)+(-3\times x)+(-3\times -9)\\\\(x-3)(x-9)=x^2-9x-3x+27=x^2-12x+27$

Now, let us multiply the result with the remaining binomial. Multiplying each term of the trinomial with each term of the binomial, we get:

$(x^2-12x+27)(x-4)\\\\= (x^2\times x)+ (x^2\times -4)+(-12x\times x)+(-12x\times -4)+(27\times x)+(27\times -4)\\\\=x^3-4x^2-12x^2+48x+27x-108\\\\=x^3-16x^2+75x-108...........(\because-12x^2-4x^2=-16x^2,48x+27x=75x)$

Therefore, the equivalent expression after expanding is given as:

$(x-3)(x-9)(x-4)=x^3-16x^2+75x-108$

Jan,Mya, and sara ran a total of 64 miles last week. Jan and Mya ran the same number of miles. Sarah ran 8 less miles than Maya.

BaLLatris [955]

<span> Jan, Maya and Sarah run a total of 64 miles per week
How many miles did Sarah run if she ran less than 8 miles compare to Maya and Jan
Jan and Maya = x
Sarah = x
Total miles = 64

=> 64 = x + x + x-8
=> 64 = 3x – 8
=> 72 = 3x
=> x = 24
Since Jan and Maya ran the same miles, they ran 24 miles each
Since Sarah is 8 less than Maya’s and Jan’s ran each
=> x – 8
=> 24 -8
=> 16
Sarah ran 16 miles in a week.
