The percentage decrease is 16.667%
72-60=12
12/72 =0.166
0.1666×100%
16.667%
Let's take this step by step. First, let's find the area of the triangle:

Small rectangle:

Big rectangle:

Let's add all the areas up:

So, your answer is:
The area of this figure is
92 cm².
Step-by-step explanation:
x^3+x^2+4x+4=0
x³+x²+4x=-4
x(x²+x+4)=-4
either
x=-4
or
x²+x+4=-4
x²+x+4+4=0
x²+x+8=0
comparing with ax² +bx+c
a=1
b=1
c=8
x={-1±√{1²-4×1×8}}/2×1
x={-1±√{-31}}/2
Step-by-step explanation:
4) 24/30=4/5
5) 2/24=1/12
6)14/84=1/6
7) 20/45=4/9
8)7/49=1/7
The product of (3 x 109) and (2 x 109) in scientific notation is 6*10^9
<h3>What is
scientific notation?</h3>
scientific notation can be described as the expression in the form a x 10^b where a is a number or decimal number a is greater than or equal to one.
(3 x 109) * (2 x 109) =6*10^9
Therefore, option D is correct.
