x(x + 1) = 72
Expanding the brackets, we get:
x^{2}+x=72
Subtracting 72 from both sides, gives:
x^{2}+x-72=0
This is the required equation to be factored and solved .
length = 1/2 w+9
perimeter= 60 =2(l+w)
substitute in for length
60 = 2(1/2 w +9 +w)
60 = 2 (3/2 w +9)
distribute
60 = 3w + 18
subtract 18 from each side
42 = 3w
divide by 3 on each side
14 = w
length = 1/2 w + 9
length = 1/2 (14) +9
7 + 9
16cm
I think the answer is A. But I’m not fully sure
Answer :Solve 2x 3y 11 and 2r - 4y24 and hence find the value of 'm' for which yemx+3. alu
