They are similar triangles so 20/4=15/x
solve for x
20x=15*4=60
x=3
Answer:
the answer is b.1001 as the equvalent number to the decimal 9
A = L * H
A = 65
L = 2H - 3
65 = H(2H - 3)
65 = 2H^2 - 3H
-2H^2 + 3H + 65 = 0
(-Hh + 13)(H + 5) = 0
-2H + 13 = 0
-2H = -13
H = -13/-2
H = 6.5 <== height is 6.5 inches
H + 5 = 0
H = -5....this wont work because it is negative
L = 2H - 3
L = 2(6.5) - 3
L = 13 - 3
L = 10 <== length is 10 inches
Answer:
Yes, it's linear.
Step-by-step explanation:
As long as it follows Y = a + bx (It's commutative so you can swap the order)
(Note: It's not squared, square rooted, etc.)
So you subtract 75 from 15 and you will get the difference and the answer is 60
