Answer:
=3x+27y−6
Step-by-step explanation:
3(3x−(2−6y+2x)+3y)
=(3)(3x+−2+6y+−2x+3y)
=(3)(3x)+(3)(−2)+(3)(6y)+(3)(−2x)+(3)(3y)
=9x−6+18y−6x+9y
=3x+27y−6
Answer:
edge of the cube is doubled. say it is represented by a.
so edge of the cube becomes 2a.
new surface area (S. A1) of the cube is
=6(2a)2=6(4a2)=24a2 sq.

The total votes are 50. If you are finding out the percentage of students that did not choose the Tigers, you would subtract the Tigers votes from the total. 50-14 =36. 36/50 would equal .72, turn that into a percent and you have 72% of students not voting for Tigers.
For First Question:
As, we find the value of x for parallel condition of line a and b
so, m∠3 = m∠1 and m∠2 = 180°-m∠1 = 180°-(2x+15)° [ As straight line contain total 180°]
Now,
m∠2 = <span>m∠6 [ Because they are corresponding angles]
180</span>-(2x+15)=(3x+10)
180=3x+10+2x+15
x= 31 satisfies the condition of a||b
For second Question:
As, it is issoceles triangle So side AC = side BC So, m∠A=<span>m∠B
</span>4x+5=5x-1
x=6
So,
m∠A=29° and triangle contain total 180°
<span>m∠C=180-29-29
</span> =122°
Option D is correct
Answer:
x=-1
Step-by-step explanation:
7x + 8 − 3x = −6 + 10
4x+8=4
4x=4-8
4x=-4
x=-4/4
x=-1
