Answer:
Second one
Step-by-step explanation:
when someone says a number squared or cubed, or to the certain power, it means how many times you multiply the base number by itself that many times, for example
2²= 2 * 2
or 9³ = 9 x 9 x 9
a square root or cube root, is a harder to understand, but still somewhat simple, it basically means how many what number squared or cubed equals this number.
so for example the square root of 9 = 3 because 3 x 3=9
or cube roots for example ∛125= 5 because 5 x 5 x 5
So here is an example one for you. √81.
What's the percentages?? I need to know that first
Step-by-step explanation:
3(t+5) = 9
3t+15 = 9
3t = -6
t = -2
2(f-7) = -10
2f - 14 = -10
2f = 4
f = 2
-(c - 9) = 4
-c + 9 = 4
-c = -5
c = 5
-6(2t + 8) = -84
-12t - 48 = -84
-12t = -36
12t = 36
t = 3
-10 (s + 2) = -57
-10s - 20 = -57
-10s = -37
s = 3.7
7(3w + 8)/3 = -9
By cross multiplication,
7(3w + 8) = -27
21w + 56 = -27
21w = -83
w = -3.95
35/5 = (F - 32)/9
7 = (F - 32)/9
By cross multiplication,
63 = F - 32
63 + 32 = F
95 = F
