The answer is a because there is not an 8 on the chart
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:
24
Step-by-step explanation:
600/25
25 goes into 600 24 times
so 600/25 could be reduced to a whole number, 24
Answer:
(y - 18) = -3/2 (x - 12)
Step-by-step explanation:
125% of 12 equals 15
75% of 18 equals 13 1/2
so the slope equals 4.5/-3 or -3/2
7 = -16t2 + 16t + 3
7 = t2 + 3
7 -3 = t2 + 3 - 3
4 = t2
square root of 4 = square root of t2
2 = t
2 seconds
