The estimate of the sum of 202 and 57 is 260. You add the numbers together and than round up.
Yes 8.54 as rational number because in can be written as 854/100
Answer:
w² +9w +20
Step-by-step explanation:
Multiply it out, collect terms, and write as descending powers of w.
(5+w)(w+4) = 5w +5·4 +w² +w·4
= w² +9w +20
Answer:
The slope is 5/-2.
Step-by-step explanation:
Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.
11 - (-4) = 11 + 4 = 15
-2 - 4 = -6
Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2
Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.
