Answer:
54
Step-by-step explanation:
60% of 90 = 60/100 × 90
= 0.6 × 90
= 54
Therefore, 60% of 90 is 54.
58%-62%
just add 2 to 60
and subtract 2 from 60 to find the range of percents
Answer:
so lets just rewrite it with A=-3 amd B=-2
(-9^4^-9^2^5)^2
which is equal to... 1!
Hope This Helps!!!
Answer:
( a+b) (a-b)
x^2 - 50
Step-by-step explanation:
The formula for difference of squares is
a^2 - b^2 = ( a+b) (a-b)
121x^2 -144 = (11x)^2 - 12^2 so this is the difference of squares
x^2 - 16y^2 = (x)^2 - (4y)^2 so this is the difference of squares
9x^2 -64 = (3x)^2-8^2 so this is the difference of squares
x^2 - 50 = (x)^2 - 2*(5)^2 this is not the difference of squares
