21/50; 420/1000=42/100 simplify it and it is 21/50
Answer:
- D
- B
Step-by-step explanation:
You may find this easier if you distribute the minus sign first.
<h3>1)</h3>
2a^2 -3ab +5b^2 -a^2 +2ab -3b^2
= (2 -1)a^2 +(-3+2)ab +(5 -3)b^2
= a^2 -ab +2b^2 . . . . . matches choice D
__
<h3>2)</h3>
6x -3 -2x +2
= (6 -2)x +(-3 +2)
= 4x -1 . . . . . matches choice B
where is the example
I can't answer the question without the example provided, but here are some steps to solve it.
Basic info-
Circumference (C)
3.14 is used for pi π= 3.14
The line halfway of the circle is the radius(r)
The line through the circle is the diameter(d)
<em>Formulas</em><em>:</em>
C= 2πr
2 × 3.14 × the radius
OR
C= πd
3.14 × the diameter
Answer:
do 0+_5 and _2+4 answer will come 11 or 18
