Answer:
3) = A+ D 4)= A and C
Step-by-step explanation:
Answer:
2) Add 21 to both sides
Step-by-step explanation:
When solving for , our goal to isolate such that we have set equal to something.
Therefore, we want to start by adding 21 to both sides. This leaves us with and we are one step closer to isolating .
The answer is D. To solve 3/5 ÷ 4/7 you would change it to 3/5 × 7/4.
Answer:
D. The correct value of c = 7.4
Step-by-step explanation:
According to Tangent-Secant theorem:
"When a tangent and a secant are drawn from one single external point to a circle, square of the length of tangent segment must be equal to the product of lengths of whole secant segment and the exterior portion of secant segment."
Here, the external length of tangent segment = 10
Also, the length of internal segment is 14 and c.
So, by the SECANT THEOREM:
or, c = 7. 1428
Now, rounding off the value of c = 7. 14 to the nearest tenth, we get
c = 7. 4
Hence the correct value of c = 7.4
