Given/equations formed from text:
I: l=w+3
II: A=l*w
III: new area B=(l-2)*w
IV: B=A-30
substitute l in II with I to remove l:
II': A=l*w=
(w+3)*w=
w^2+3w
substitute l in III with I to remove l:
III': B=(l-2)*w=
(w+3-2)*w=
(w+1)*w=
w^2+w
substitute A and B from II' and III' into IV:
B=A-30
w^2+w=w^2+3w-30
30=2w
w=15
insert w=15 into I:
l=15+3=18
->
A) dimensions of full size rectangle are width 15 and length 18
dimensions of reduced size rectangle are width 15 and length 16
B) full size: 15*18=10*18+5*18=180+90=270cm^2
reduced size: 15*16=10*16+5*16=160+80=240cm^2

<span>Need
to write a decimal which is the value is 1/10 as much as the value of the other
digit.
=> 1/10 is equals to 0.1
Thus, we need to find a decimal that the value of the digits are 1.10 greater
than each other.
Since we have 0.1 already as decimals, simply divide 0.1 again with 10 to get
the answer
=> 0.1 / 10
=> 0.01
Now, let’s add the 0.1 and 0.01
=> 0.11
Thus, the decimal that are 1/10 greater than the other digit next to it is
0.11.

Answer:
C. 4i
Step-by-step explanation:
√-1 is imaginary number i
Step 1: Write expression
√-16
Step 2: Factor
√-1 · √16
Step 3: Simplify
i · 4
4i
Step-by-step explanation:
don't panic. just breathe and think logically.
why would these angles be different ? how could they be different ?
right : they cannot be different. otherwise the 2 horizontal lines would not be parallel.
so, yes, indeed, these 2 angles are identical.
3x + 2 = 2x + 6
x = 4
that's it.
