Answer:
$2.40
Step-by-step explanation:
Zack needs a total of 4 feet of balsa wood which costs $0.05 per inch.
Note that 4 feet = 48 inches.
The overall cost will be ($0.05/in)(48 in) = $2.40
Answer:
C
Step-by-step explanation:
the sum of complementary angles = 90°, hence
x + 5 + x - 9 = 90
2x - 4 = 90 ( add 4 to both sides )
2x = 94 ( divide both sides by 2 )
x = 47
Thus ∠DFG = 47 + 5 = 52° and ∠JKL = 47 - 9 = 38°
Answer:
Perimeter of the rectangle=6x+8 square units
Step-by-step explanation:
Given that area of rectangle is 
Area of rectangle=lw square units
Comparing the above equation with the given area we get
lw=(x+3)(2x+1)
Therefore length=x+3 and width=2x+1
To find the perimeter :
Perimeter of the rectangle=2(l+w) square units
Therefore perimeter of the rectangle=6x+8 square units
If you don't want to express this into fractions, then you take the inverse of the exponents in your denominator. For example, 8 would be 8^-1, x^4 would be x^-4, y^3 would be y^-3 and z would be z^-1. Then, just multiply all of them. The final answer would be
3 x 8^-1 x a²b³c^5x^-4y^-3z^-1
I hope my explanation helped you understood the solution :)
