Answer:

235.75 square feet

Step-by-step explanation:

15 inches on all sides, means 30 inches more on side a and side b.

30 inches converted to feet is 2.5.

side a: 18 feet + 2.5 feet =20.5 feet

side b: 9 feet + 2.5 feet = 11.5

multiply both sides

20.5 * 11.5 = 235.75 square feet

Marge cut 16 pieces of tape for mounting pictures on poster board. Each piece of tape was 3/8 inch long. How much tape did Marge
mafiozo [28]
Hi! :)

It sounds like you need to multiply this fraction. 

\frac{3}{8}*16=6

So, Marge used 6 total inches of tape. 

Hope this helps!

Construct a polynomial function with the following properties: third degree, only real coefficients, −3 and 3+i are two of the z
irina [24]

Answer:

\boxed{-3(x+3)(x^2-6x+10)}

Step-by-step explanation:

Hello,

As the polynomial has only real coefficients, it means that 3-i is a zero too, because we apply the Conjugate Zeros Theorem.

It means that we can write the expression as below, k being a real number that we will have to identify.

k(x+3)(x-3-i)(x-3+i)=k(x+3)((x-3)^2-i^2)\\\\=k(x+3)(x^2-6x+9+1)\\\\=k(x+3)(x^2-6x+10)

And for x = 0, y = -90 so we can write

-90=k*3*10, meaning that k=-3

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
