Answer: (-∞,∞)
Step-by-step explanation:
f(x)=4x+19
g(x)=12x+14
f + g= 4x +19 + 12x + 14 = 16x + 33
Domain of 16x + 33 = (-∞,∞)
The formula for calculating the perimeter (p) of a rectangle is 2 lengths (l) plus 2 widths (w). Mathematically, p = 2l + 2w
If the length is 5 cm longer than the width, then l = w + 5.
Divide 914/420, move the decimal over to the right two places and you'll get approximately 217.5%
EDIT: My mistake, read question wrong.
![914-420 = 494](https://tex.z-dn.net/?f=914-420%20%3D%20494)
![494/420 = 1.17](https://tex.z-dn.net/?f=494%2F420%20%3D%201.17)
<u></u>117.62%
Subtract the difference and divide by original number (: Move decimal place over two places.
ABC is similar to PQR
that means AC/PR is a constant = 12/ 6 = 2
AC= 2 PR
AB= 2PQ
BC= 2QR
Perimeter of ABC= AB+BC+ CA=
2PQ + 2 QR + 2PR= 2( PQ+ QR+ PR)
= 2( perimeter of triangle PQR )
Perimeter of ABC= 2( perimeter of PQR) = 2* 36 = 72
Answer : 72.
