Are those supposed to be exponents? When multiplying exponents you add them together
b^3 * b^1 * b^4 * b^2
3 + 1 + 4 + 2 = 10
Answer: b^10
Mike has 78 feet of fencing available for his garden, this is the perimeter (P) of the rectangle:
Perimeter: P=78 feet
The formula of Perimeter is:
P=2(W+L), where W is the width and L is the length, then:
P=78→2(W+L)=78
Dividing both sides of the equation by 2:
2(W+L)/2=78/2
W+L=39
If the shape is of a golden rectangle, we know:
L=1.6W
Replacing this above:
W+1.6W=39
Adding similar terms:
2.6W=39
Solving for W
2.6W/2.6=39/2.6
W=15 feet
L=1.6W=1.6(15)→L=24 feet
Answer: T<span>he dimensions of the garden are: Width=15 feet and Length=24 feet. </span>
Answer:
2x²+ 7x + 12
Step-by-step explanation:
2x(x+5)-3(x-4)
2x²+ 10x - 3x +12
2x²+ 7x + 12
The other side is x^2+9
x^3-27/x-3= x^2+9
Answer:
28
Step-by-step explanation:
you could wright the equation like 15/100=4.20/x
All I did is 100 divided by 15, which is 6.6666667, and then multiply that number by 4.20.
I hope this helped you!
