Hi!!
Could u please help me with this qs?
Factorize: (8-b)(3+b)
And please mention the property or identity to be used too

24 + 5b -b²

Step-by-step explanation:

i am not sure what is meant by propert/ identity but

8 x 3 = 24

8 x b = 8b

(-b) x 3 = (-3b)

(-b) x b = (-b)²

24 + 8b + (-3b) + (-b)²

24 + 5b - b²

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
