P = 2L +2w = 58 ----> L+w = 29 ----> L = 29-w
A = L*w = 204
Now substitute "29-w" for L in Area equation:
(29-w)w = 204
This gives a quadratic
w^2 - 29w + 204 = 0
Use quadratic formula:
w = 12, w = 17
Either value will work since L=29-w, the other number becomes length.
Therefore the final dimensions of the rectangle are 12 by 17.
I assumed you meant "What is 300 <em>to </em>the power of two," or 300².
We can think of exponents as repeated multiplication in the same way as we think of multiplication as repeated addition: Just as 300 · 2 means 300 + 300, 300² means 300 · 300.
When we work this out, we find that 300² = 300 · 300 = 90,000
Answer:
$26
Step-by-step explanation:
15 * 2= 30
30-4= 26
Answer:
Ok so the b is a coefficient which means it needs to be replaced by a number.
The 7 is gonna be multiplied by that coefficient then subtracted by 3.
