Answer:
(10x + 8) is the polynomial expression for the perimeter of the blanket.
Step-by-step explanation:
The height and width of the rectangular blanket are (2x - 3) cm and (3x + 7) cm respectively.
Now, the perimeter of a rectangle having height h and width w is given by
P = 2h + 2w
⇒ P = 2(2x - 3) + 2(3x + 7)
⇒ P = 4x - 6 + 6x + 14
⇒ P = 10x + 8.
So, this is the polynomial expression for the perimeter of the blanket. (Answer)
Answer:
D. Y+5=-(1/2)*(x+3)
Step-by-step explanation:
Perpendicular Lines are those with the following condition:
y=a*x+b (1)
y=c*x+d (2)
Where 'a' and 'c' are the respective slope
If These two lines are perpendicular, then
a=- 1/c
Equation (1) for our case is written as y=2x-8, meaning that a=2 and b = -8
Using those principles we have that the slope for our needed line ('c') has to be -(1/2).
Now we most use the given point to find the remaining term of the equation (d) so, evaluate (-3,-5) in eq (2) to have this:
-5=(-1/2)*(-3)+d
resulting that d=-5-(3/2)
Eq (2) is written now as the following: y= (-1/2)*x - (5+3/2)
Rearranging terms, we have the following:
y+5=(-1/2)*x-(3/2)
where you can obtain a more pretty expression:
y+5=(-1/2)*(x+3)
5 + 6 − 1 2 − 1 1 -11y 5+6y−12−11y − 7 + 6 − 1 1
− 7 + 6 − 1 1 −7+6y−11y − 7 − 5
− 7 − 5 −7−5y − 5 − 7
Solution: −5y−7
