Answer:
The area of the base plate is 120 in
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
euhm ... did u just asked if a figure with h=9inches and b=12inches is rectangular???
Does it matter what the diagonals are etc?
if the frame has angles of 90° and it has two different lengths then it has to be rectangular. The sides of a square would have the same lengths.
Step-by-step explanation:
the area of this rectangle is
(10 + 2x)(8 + 2x) = 168
80 + 20x + 16x + 4x² = 168
4x² + 36x = 88
because for the whole length you need to add x twice (left and right). the same for the width (top and bottom).
Your answer is c 10x + 15
5 time 2x is 10x plus 5 times 3 is 15 because you multiply the 5 with everything inside the parentheses. so your equarions should look like 10x + 15
For this case we have:
By definition, two points are needed to find the equation of a line. We have a series of points given by:
We chose two points:
By definition, the formula of the slope is given by:
Substituting:
Being a line of the form 
, we substitute a point and the slope found to find the cut point b.
Thus, the equation of the line is given by:
Answer:
Option C
