Q4, 4y²=60
y=√15 ( i am not sure)
q6, (5+y) ²=81
5+y=9
y=4
q7 (x+4) (x) =77
x²+4x-77=0
(x+11) (x-7) =0
x=-11(rej) or x=7
therefore ,length= 7+4=11cm
breadth=7cm
Answer:
B
Step-by-step explanation:
let's represent the width with x, if we represent the width with x then that makes the length x+4. Therefore the perimeter would be 2x+2(x+4)=48
Answer:
C. 15
Step-by-step explanation:
A straight line equals 180°.
The angles are:
(6x + 10) +
(6x - 10)
+10 and -10, cancel each other out.
Now we are left with:
(6x) +
(6x)
6 + 6 = 12, so we have 12x
180° ÷ 12 = 15°

Answer: C {16, 17, 18, 19, 20}</h3>
The instructions state "there are a minimum of 16 players and at most 20 players on the team". This means that we have between 16 and 20 players, inclusive of both endpoints. Therefore, x can take on any whole number between 16 and 20. The domain is the set of allowed x inputs of a function.
