Answer:

a=3

Step-by-step explanation:

<u>Intersecting Secants Theorem</u>

If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.

Applying the theorem of Intersecting Secants in the diagram

$TV\cdot UV=SV\cdot RV$

$a*12=4X9\\12a=36\\a=36\div12\\a=3$

Therefore, the value of a=3

The area of a square mural pointed on the side of a building is 110 square feet. What is the best estimate of the side length of

natka813 [3]

Answer:

C

Step-by-step explanation:

Area of a square equals to the square of its side, therefor the side of a given area for a square is the square root of the area.

$A = a^{2}\\a = \sqrt{A}\\a = \sqrt{110} = 10.48 ft$

Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -3x - 2

5x + 2y = 15

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

Substitute in <em>y</em>: 5x + 2(-3x - 2) = 15
Distribute 2: 5x - 6x - 4 = 15
Combine like terms: -x - 4 = 15
Isolate <em>x</em> term: -x = 19
Isolate <em>x</em>: x = -19

<u>Step 3: Solve for </u><em><u>y</u></em>

Define original equation: y = -3x - 2
Substitute in <em>x</em>: y = -3(-19) - 2
Multiply: y = 57 - 2
Subtract: y = 55
