Answer:
<h2>FD = 26</h2>
<u>Step-by-step explanation:</u>
CD = ED --- (secant<em> </em>property<em>)</em>
so, ==>>
13x - 16 = 4x + 11
13x - 4x = 11 + 16
9x = 27
x = 27÷9
x = 3
side ED = 4x + 11 = 4×3 + 11
side ED = 23
side FE = 12
ΔFED = 90° ...... (tangent secant property)
so.........
FE² + ED² = FD² ......... ( by pythagoras theorm)
12² + 23² = FD²
144 + 529 = FD²
673 = FD²
√673 = FD
26 = FD
Positive 10 more than -10
Answer:
Combining like terms is just that, combining numbers in an equation that have the same property. examples would be constants or numbers with the same exponent.
Properties of exponents are when you multiply, add, subtract, or divide exponents.
I hope I helped!
<span>f(x)=2x+1 and g(x)=x^2-7
(f+g)(x) = </span>2x + 1 + x^2 - 7
(f+g)(x) = x^2 + 2x - 6
answer
x^2 + 2x - 6
