Answer:

x = 12

Step-by-step explanation:

(whole secant) x (external part) = (whole secant) x (external part)

(6+x) *6 = (4+23) * 4

(6+x) *6 = 27*4

6(6+x) = 108

Divide each side by 6

6+x =18

Subtract 6 from each side

6+x-6 =18-6

x = 12

Answer:

684 ft^2

Step-by-step explanation:

You can find the area of the middle rectangle by using:

$A=LW$

$A=18*20$

$A=360$

You can find the area of a triangle by using:

$A=\frac{BH}{2}$

Triangle 1: A=90

Triangle 2: A=72

2(72+90)+360

324+360

684

If f(x) = 4x - 3, what is (f^-1 o f)(10)?

RSB [31]

F(x)=(4x-3)^-1(10))
(-4x+3(10))
(-4x(30))
i think that's how you would solve it i can't quite remember if you substitute the x with the 10 but if you do it would be
f(x)=4(10)-3
40-3
37
but im pretty sure it's the first way.

Answer:

Angle A is 101

Angle B is 79

Angle C is 83

Angle D is 97

Step-by-step explanation:

Vertical angles are congruent, which applies to C.

Lines are parallel so 79 and angle B are the same

Angle a is 101 because its a supplementary angle

Angle D is 97 because its also a supplementary angle so you subtract 83 from 180.
