Answer:This is a tricky question that Reina and Sam are multiplying (84)5 (73)9 and their work are (84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's (84)5 (73)9 = 84-573-9 = 820727 Sam's Actually they are doing or multiplying using exponents. Reina's work (8*)s(7³)º=8*+5+ 73+9= 8° 712 This is incorrect because she added exponents instead of multiplying exponents Sams work (8*)5 (7³)º=84x5 73x9= 820 727 This is correct because Sam multiplied exponents correctly Exponents are multiplied not added.
Answer:
10x - 20
Step-by-step explanation:
<em>Distribute 5 </em>to <em>each</em> of the terms within the parentheses to get 5(2x) - 5(4) = 10x - 20.
X Coordinate: (-3a + 3a)/2
0/2 = 0
Y Coordinate: (b + b)/2
2b/2 = b
Midpoint: (calculated x, calculated y)
In this case, the midpoint should be (0, b)
Answer:
x = 12
Step-by-step explanation:
Subtract 3 from both sides
p.s. it would be 18 if it was x-3 = 15
