Step-by-step explanation:

r=-6/1=-6

$S_{7}=a\frac{1-r^n}{1-r} =1\frac{1-(-6)^7}{1-(-6)} \\=\frac{1+6^7}{1+6} \\=\frac{1+279936}{7} \\=\frac{279937}{7} \\=39991$

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:

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

What is 10+3c+5d-7c+d

kumpel [21]

Hey!

To simplify the equation provided we must first start off by grouping like terms.

Original Equation :
10 + 3c + 5d - 7c + d

New Equation {Grouped Like Terms} :
3c - 7c + 5d + d + 10

Now we add similar elements.

Old Equation :
3c - 7c + 5d + d + 10

New Equation {Added Similar Elements} :
-4c + 5d + d + 10

Next we add the other similtar elements.

Old Equation :
-4c + 5d + d + 10

New Equation {Add Similar Elements} :
-4c + 6d + 10

So, this means that the equation 10 + 3c + 5d - 7c + d simplified is -4c + 6d + 10.

Hope this helps!

Ive never seen a question like this tbh

The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.

A=1/2(9)(4)

Multiply to get 18 square cm, which is choice D.
