Answer:
There are two roots: -3 and 3
Step-by-step explanation:
Combine the like terms first. We get u^2 = 9.
There are two roots: -3 and 3.
They are similar, though not congruent. They have some differences between angles.
(All this Web playing has paid off...)
BTW, Web is a Brainpop game about angles.
First find the volume of the block(s):
A=s^3
s=side length
A=1^3
A=1 cubic inch
Next, find the volume of the shoe box:
12*6*5
360 cubic inches
Finally, divide the volume of the larger box by the volume of the block to get how many blocks will fit:
360/1 = 360 blocks
Answer:
The parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.
Step-by-step explanation:
Given the parallelogram with sides 20 and 21 units with diagonal length 28 units.
we have to tell it is a rectangle or not.
The given parallelogram is rectangle if the angle at vertices are of 90° i.e the two triangle formed must be right angles i.e it must satisfy Pythagoras theorem
=
+
784=400+441=881
Not verified
∴ The sides of the parallelogram do not meet at right angles.
Hence, the parallelogram is not rectangle because the sides of the parallelogram do not meet at right angles.
