Answer:
<em>780cm cubed</em>
Step-by-step explanation:
- <em>if we want to find the volume we would do length x width x height</em>
- <em>which would be 5 x 12 x 13</em>
- <em>so we would do 5 x 12 which is 60 </em>
- <em>then we would do 60 x 13 which equals 780</em>
- <em>So the answer is 780</em>
- <em>Since this is volume it would be 780cm cubed</em>
Answer:
x = -2+√3i and -2-√3i
Step-by-step explanation:
The formula for the general formula is expressed as;
x = -b±√b²-4ac/2a
Given the expression
x²+4x+7 = 0
a = 1, b = 4 and c = 7
Substitute
x = -4±√4²-4(1)(7)/2(1)
x = -4±√16-28/2
x = -4±√-12/2
x = -4±√4*-3/2
x = -4±2√-3/2
x = -4±2√3i/2
x = -4+2√3i/2 and -4-2√3/2
x = -2+√3i and -2-√3i
Answer:
Yes
Step-by-step explanation:
Because a dollar and a dime and 11 dimes are equal in value ($1.10)
And they exchange 1 dollar and 10 dimes which is also the same amount. So they will be the same.
