Answer:
$36.8
Step-by-step explanation:
Answer:
25
+5ab+
Step-by-step explanation:
1. First, write out the expression without the square
2. Then use foil to multiply:
5a*5a+5a*
+*5a+*
=25+5ab+
3. That is your answer.
Simultaneous Equations
2u + b = $110
4u + 3b = $268
(x2) 4u + 2b = $220
(x1) 4u + 3b = $268
<em />If both the matching coefficients are the same, we subtract equation 2 from equation 1
2b - 3b = -b
$220 - $268 = $-48
-b = -$48
b = $48
If you want to find out what a unicycle costs...
Substitute b = $48 into the first equation
2u + $48 = $110
Balance the equation, whatever happens on one side, happens on the other.
2u + $48 (-$48) = $110 (-$48)
2u = $62
2u(/2) = $62(/2)
u = $31
Answer:
132 inches
Step-by-step explanation:
We need to multiply both units together; there are 12 inches in a foot and 11 feet. Therefore:
11x12=132
132 inches
