Answer : A 

Take square root for each term and simplify it




so we will get


Answer:
Step-by-step explanation:
There are 10 cubes all together.
You want blue and then red with replacement.
Blue
P(B then red) = 3/10 * 4/10 = 12 / 100
12/100 reduces to 3/25
The answer is A
18/5 as a mixed number is 3 3/5
Area of paralellogram=legnth times height
l=legnth
h=height
area=96
lh=96
h is 4 less than l
h=-4+l
sub
l(-4+l)=96
-4l+l^2=96
minus 96 both sides
l^2-4l-96=0
factor
(l-12)(x+8)=0
set to zero
l-12=0
l=12
l+8=0
l=-8, imossible, legnth cannot be negative, disreagard this soultion
legnth=12cm
Answer:
30%
Step-by-step explanation:
Selma spent 3/10 of her allowance on a new backpack.
Hence, the percent of her allowance that she spent is calculated as:
Fraction of allowance spent on Backpack × 100
= 3/10 × 100
= 0.3/1 × 100
= 30%
Therefore, Selma spent 30% of her allowance on a new backpack.
