Answer:
3x6+3x1+4x3
Step-by-step explanation:
Answer:
14x + 4
Step-by-step explanation:
3(4x+2) + 2(x-1)
Distribute by multiplying into the bracket
=12x + 6 + 2x - 2
Group like terms by adding and subtracting
= 14x + 4
common difference, d = -3
f1 = -13
An arithmetic sequence f(n) = f1 + d(n - 1)
so f(n) = -13 - 3(n - 1)
f(46) = -13 - 3(46-1) = -13 -3(45) = -13 - 135 = -148
Answer:
f(46) = - 148
Answer:
420
Step-by-step explanation:
Each of the 7 appetizers can be paired with one of 10 entrees, and each entree can be paired with one of 6 desserts. So the number of combinations is:
7 × 10 × 6 = 420
Answer:
ZB = 54
Step-by-step explanation:
Complementary angles add to 90 degrees
ZA + ZB = 90
x-15 + x+3 = 90
Combine like terms
2x-12 =90
Add 12 to each side
2x-12+12 = 90+12
2x = 102
Divide by 2
2x/2 = 102/2
x = 51
We want to find the measure of ZB
ZB = x+3
ZB = 51+3
ZB = 54
