Use the Pythagorean Theorem. a^2+ b^2=c^2.
In this case, it is c^2-b^2=a^2, so your answer is 4.686 mm^2. Round if you need to.
Answer:
x = 21/4
Step-by-step explanation:
re-arrange the equation
-4+5x-7-3x = 10-2x (move 3x to the other side)
-4+5x-7-3x+2x = 10 (move 2x to the other side)
5x-7-3x+2x = 10+4 (move 4 to the other side)
5x-3x+2x = 10+4+7 (move 7 to the other side)
4x = 21 (add up both sides)
x = 21/4 (divide both sides by 4
Step-by-step explanation:
The domain of f(x) = 0.5^x is all values of x and the range is f(x)>0 as 0.5^x cannot be negative or zero. In interval form this is Domain is (-∞, ∞) and Range is (0, ∞).
Answer:
L = 19 yd
W = 15 yd
Step-by-step explanation:
2L + 2W = 68
L = W + 4
Substitute for L in the first equation
2(W + 4) + 2W = 68
2W + 8 + 2W = 68
4W = 60
W = 15 yd
Plug W in the second equation to find L
L = W + 4
L = 15 + 4
L = 19 yd
Plug both answers in both equations to check
First equation = 2 (19) + 2 (15) = 68
Second equation = 19 = 15 + 4
Hope that helps!
