blagie [28]

Answer:

Catherine is not correct (see the explanation)

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

the two points from the graph are

(4,40) and (7,70)

substitute the values in the formula

m=\frac{70-40}{7-4}\\m=\frac{30}{3}\\m=10

therefore

When the factors of a trinomial are (x+p) and (x-q) then the coeffcient of the x term in the trinomial is?
Tatiana [17]
The coefficient is:  "1" .
____________________________________________________
          Note:  There is an "<u>implied coefficient</u>" of "1"; since "1",  multiplied by any value, is equal to that exact same value; by convention, we eliminate the "1" as a coefficient.
____________________________________
Further explanation:
____________________________________
(x+p)(x−q) = x² − xq + px − pq ;
____________________________________

(x+p)(x−q) =  {using "FOIL" → "First, Outer, Inner, and Last" terms}:
____________________________________
<u>F</u>irst:    x*x = x² ;

<u>O</u>uter: x*(-q)= -xq ;

<u>I</u>nner:  p*x = px ;

<u>L</u>ast:   p*(-q) = -pq
_________________________________
  (x + p)(x − q) = x² − xq + px − pq .

Angie is wrapping a present for her best friend. The box is 16 inches long, 12 inches wide, and 3 inches high. How many square i
rjkz [21]
I'm assuming the box is a rectangular prism:
They're asking for the surface area so the answer should be 48*2 + 192*2 + 36*2 since it has 6 faces so S.A. = 552 square in.
