Let the positive number be
The expression is
⇒ expanding the bracket gives,
⇒ rearranging to equate one side to zero
⇒ Dividing each term by 7 to simplify
⇒ Factorising gives
and
Hence, the first number is -5 and the second number is 3
Answer:
<h3>6</h3>
Step-by-step explanation:
Given the expression sin(9z − 1) = cos(6z + 1), for 0 < z ≤ 90, we are to find z
Note that sin theta = cos(90-thetsa)
sin(9z − 1) = cos(6z + 1)
cos (90 - (9z-1)) = cos(6z + 1)
cos (90 - 9z+1)) = cos(6z + 1)
cos (91-9z) = cos(6z + 1)
Cos will cancel out to have;
91-9z = 6z+1
-9z - 6z = 1-91
-15z = -90
z = 90/15
z = 6
Hence the value of z is 6
Ummmmmm whatttt I’m confuseddd
Answer:
Mona = 8, Shakira = 16
Step-by-step explanation:
S = 2m....m = S/2
2S + S = 24
3S = 24
S = 24/3
S = 8
Mona = 8
Shakira = 16
Step-by-step explanation:
9 = 9 , 25 = 5 , 36 = 36
