Bill's typing speed is 58 words per minute.
Step-by-step explanation:
<u>Given : </u>
Bill can type 19 words per minute faster than bob. their combined typing speed is 97 words per minute.
<u>To Find : </u>
Bobs typing speed
<u>Solution : </u>
Let the bobs typing speed is x
According to the given question :
Bobs typing speed is x
Bill's typing speed is 19+x
Their combined speed is 97 words per minute.
<u>Solving value x : </u>
x + 19+x = 97
2x + 19 = 97
2x = 97 - 19
2x = 78
x = 78/2
x = 39
Bobs typing speed = 39
Bill's typing speed 39 + 19 = 58
Hence, Bobs speed is 39 words per minute.

Answer:
x^2+10x+16
Step-by-step explanation:
Plug in the values
h=x+8
b=2x+4
A=1/2(2x+4)(x+8)
A=(x+2)(x+8)
FOIL: x^2+8x+2x+16
A=x^2+10x+16
Add the X to both sides making it 16=8x and then divide both sides by the eight giving you 2
