N^2 should be the correct answer. Based on those numbers, it appears that the sum can be found by squaring the term n
Answer:
x = -7
Step-by-step explanation:
2x+6 = x-1
add -6 to both sides
2x = x-7
add -x to both sides
x = -7
Answer:
-1

Answer:
34. E 2 1/2
36. C 6cm
Step-by-step explanation:
34. ABC's triangle has 4, as it is equivalent to ADE's triangle's 10. I added 4 and 6 because the whole triangle shown is ADE. Then I did 10/4.
36. The reasoning is that on the other side, there is 9cm and 6cm which is equivalent to AB and 4cm
It goes like: 9/6 = AB/4
9 times 4 equals 36, and 36 divided by 6 is 6. Therefore the answer is 6cm.
Answer:
90⁰
Step-by-step explanation:
y=cosx
y'= -sinx
eqñ of tangent is y=-x
slope of tangent =-1
we know...
slope of tangent = y' or derivative of y
-sin x = -1
sin x= 1
x = 90⁰
