To make one cheese sandwich, Tina uses one bread roll and two cheese slices One pack of bread rolls which contains 15 rolls is £1.91

Pack of 20 cheese slices is £2.23

She is going to buy enough packs to have exactly twice as many cheese slices as bread rolls. work out the least amount she can spend

answer: ok

step-by-step explanation:

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
