Answer:
40 15/154.
Step-by-step explanation:
idk how to explain. i did the math in my head.
L=w+4m
A=w*l
A=w(w+4)=45
w^2+4w-45=0
w^2+9w-5w-45=0
w(w+9)-5(w+9)=0
(w+9)(w-5)=0
⇒ w+9=0 or w-5=0
⇒w-5=0
w=5
l=5+4
l=9
Answer:
if u mean absolute value it is 5.
the value is always positive an dmeans how far is it from the numberline
Step-by-step explanation:
The answer is -2f -24.
All you gotta do is is combine like terms.
Explanation:
-2.4f + 0.4f = -2f
-16 -8 = -24
To concert a percentage into a fraction, first convert it into a decimal.
To change a percentage into a decimal, you have to take away the percentage sign and move the decimal point two places to the left.
Thus, 40% = 0.40 = 0.4
Now, to change the decimal into a fraction, you multiply both the numerator and the denominator (1) by 10.
0.4/1 = 4/10
However, in this case the fraction is in simplest form. To simplify a fraction, you have to divide the numerator and the denominator by the GCF, which in this case is 2.
4/10 = 2/5
Therefore, your answer is D. 2/5 off.
