12 -3 × 2.25 = 12.00 - 6.75 = 5.25 feet ;
Answer:
y=3x+3
Step-by-step explanation:
the line doesnt connect with a negative so the first and third arent it. And the line cross's with a 3 not an x so the seconds on isnt the answer. Leaving the last one the answer.
Answer:
15.62
Step-by-step explanation:
The Pythagorean theorem tells you the relation between the side lengths is ...
x^2 = 12^2 + 10^2 . . . the sum of squares of sides is the square of the hypotenuse
x^2 = 244
x = √244 ≈ 15.62
Answer:
x = 4
Step-by-step explanation:
When a tangent and a secant are drawn from an external point to a circle.
Then the product of the external part of the secant and the entire secant and the square of the measure of the tangent are equal, hence
x(x + 5) = 6²
x² + 5x = 36 ( subtract 36 from both sides )
x² + 5x - 36 = 0 ← in standard form
(x + 9)(x - 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 9 = 0 ⇒ x = - 9
x - 4 = 0 ⇒ x = 4
However, x > 0 ⇒ x = 4
