Answer:
P = 9+9+14+14= 46cm
A = Base (14 cm) × Height (7cm)
14×7= 98 cm²
3. P= 1.2 +2.0 +1.6= 4.6m
A = 1/2 B×H
= 1/2 1.6× 1.2
= 0.96 m²
Given:
The given sets are:
To find
The set 
.
Solution:
We have,
Now, is the set that contains all the common elements of both sets B and U.
Therefore, the correct option is A.
3x
What equation: y= 3x+3
That's not possible, and there is no solution. If the integers are consecutive,
then the larger one is precisely one (1) more than the smaller one.
Answer:
25a2b2+4a2b+6ab2-4ab+7
Step-by-step explanation:
=sum of two polynomials -one addend
=20a2b2-8a2b+6ab2-4ab+2-(-5a2b2+12a2b-5)
=20a2b2-8a2b+6ab2-4ab+2+5a2b2-12a2b+5
=25a2b2+4a2b+6ab2-4ab+7
