Answer:
-4 or -9
Step-by-step explanation:
-a^2-13a-36=0
(-a-4)(a+9)=0
-a-4=0
a+9=0
a= -4, -9
Each Had 10. Y= 4. Because 3 x 4 = 12 + 8 = 20 ÷ 2 = 10
Answer:
x=0
Step-by-step explanation:
Use the secant tangent power theorem. the length of the tangent (vertex to point of intersection) squared = the part of the secant outside the circle times the full length of the secant. so you have 4 * (9) = the tangent length (PQ) squared. so if 36 = PQ squared, the. PQ = 6.
