Answer:
4x² + 12x + 9
Step-by-step explanation:
<h3>
Using identity: </h3>
(a +b)² = a² + 2ab + b²
Here, a = 2x & b = 3
(2x +3 )² = (2x)² + 2*2x*3 + 3²
= (2x*2x) + 12x + 3*3
= 4x² + 12x + 9
Heya!!!
Answer to your question:
Let Adam's points be x.
Nick has points =7200=20%of x+x
20/100 *x + x=7200
x/5 +x=7200
6x/5=7200
x= 7200*5/6
x=6000
Adam has 6,000 points.
Hope it helps *_*
Answer :- Statement (B) ,C'D' ll AB
Given AB is parallel to CD. CD rotated.
Consider a transversal line <em>l </em>intersecting AB and CD at angle x.
therefore By slope formula,
slope of AB and CD = m =tanx
Now after rotation of CD become C'D'
therefore, slope of C'D' = =tanx=m
Hence C'D' ll AB.
SA pyramid+SA rectangular prism= total SA
Total SA= Area of the base+ area of the four rectangles+area of four triangles
Total SA= length^2+length*width*4+1/2(slant height)(length)*4
length=12, width=8, slant height=10
Total SA= (12)^2+4(1/2*12*10) +4(12*8)=768cm^2
so C is correct.
