Answer:
triangle and trapezoid
Step-by-step explanation:
To be able to arrange the volumes from least to greatest we must be mindful that the exponent of 10 in the scientific notation should be arranged from least to greatest also. If two or more items have the same exponents in the 10 of the scientific notation, we use the base for comparison. For this item, the arrangement should be
2.2x10^12 km³, 6.9x10^12 km³, 2.7x10^18 km³, and 4.9x10^21 km³
Thus, the answer to this item is letter B.
Answer:
-0.125
Step-by-step explanation:
Shown in the image above
X=lebgth
y=width.
I suggest this system of equations:
x=2y
(x+4)(y+4) - xy=88
we can solve this system by substitution method.
(2y+4)(y+4)-2y(y)=88
2y²+8y+4y+16-2y²=88
12y=88-16
12y=72
y=72/12
y=6
x=2y
x=2(6)=12
Answer: the dimensions of the original rectangle are:
length=12 m
width=6 m
+ 
or x = -
