So factor out the 5
5(n^2+2n+4)
this cannot be simplified unless you use quadratic formula and the answer is non-real
<u>
</u>
Answer:
Step-by-step explanation:
L = B + 5
2L + 2B = 150
Substituting gives 2B + 2(B+5) = 150
4B = 140
B=35; L = 40
Area = B x L = 35 x 40 = 1400 m2
Answer: Yes, it's true.
Step-by-step explanation:
The first step is to convert the mixed number
to a fraction. The procedure for this is:
- Multiply the whole number 1 by the denominator 5.
- Add the product obtained and the numerator 2 (This will be the numerator of the fraction).
- The denominator does not change. It will be 5.
Then:

Rewrite the equation:
Notice that the denominators on the left side are 4 and 5 and the denominator on the right side are also 4 and 5.
Then, the Least Common Denominator (LCD) on both sides is:

Now we can solve the subtraction on the left side of the equation and the addition on the righ side:

Therefore:
(IT'S TRUE)
Answer:
stuff
Step-by-step explanation:
180-72 = 108
a2 = 108º
a3 = 108
a4 = 72
a4+a6 = 180 so
a11+a13 + 180...
Not sure what it is but i love ur handwriting- u got this though
