Its the first one 5+4 equals 9

Step-by-step explanation:

? = 5

This is an exponent rule: when you multiply two exponents with the same base, the answer has the same base, and its exponent is the sum of the powers of the two exponents.

So d = 9 - 4 = 5.

i hope this helps! Sorry if it was a bit unclear.

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)

45
