Answer:
They all have 90 degrees angles and they have the same width and height they are just on different sides
Step-by-step explanation:
Answer:
Step-by-step explanation:
We know that a rational number cannot have roots. All of the answer choices cannot be simplified except for , which can become 1. Therefore, our answer is .
Answer:
x = 72
Step-by-step explanation:
Make the problem simpler by eliminating the fractional coefficients:
x-9= 1/4x + (1/4x + 12) + (1/4x - 3), when multiplied by 4, becomes:
4x - 36 = x + x + 48 + x - 12
Summing up all the x terms, we get:
4x - 2x - x = 48 - 12 + 36
Then x = 72
Answer:
Sum of cubes identity should be used to prove 35 =3+27
Step-by-step explanation:
Prove that : 35 = 8 +27
Polynomial identities are just equations that are true, but identities are particularly useful for showing the relationship between two apparently unrelated expressions.
Sum of the cubes identity:
Take RHS
8+ 27
We can write 8 as and 27 as .
then;
8+27 =
Now, use the sum of cubes identity;
here a =2 and b = 3
or
= LHS proved!
therefore, the Sum of cubes polynomial identity should be used to prove that 35 = 8 +27
X+2y=8
2y=8/2y
=4 is the answer. You’re so welcome
