Answer:
k =3
Step-by-step explanation:
2/5(5k+35) -8 =12
Add 8 to each side
2/5(5k+35) -8+8 =12+8
2/5(5k+35) =20
Multiply each side by 5/2
5/2 *2/5(5k+35) =20*5/2
5k+35 = 50
Subtract 35 from each side
5k+35-35 = 50-35
5k = 15
Divide by 5
5k/5 = 15/5
k =3
Answer:
A= 15 root 5 - 10 ÷ 41
Multiply (3 root 5 - 2) top and bottom. Simplify
B= - 2
Multiply (root 3 + root 5) top and bottom. Simplify
C= 6x - 3 root xy ÷ 4x - y
or
3x - 3 root xy ÷ 2x - y
(because 6 & 4 is Divisible by 2)
Multiply (2 root x - root y) top and bottom. Simplify
Root means a square root - so, replace the word root with a square root!
Hope this helps!
Answer:
197
Step-by-step explanation:
You have 6 sides of this object. So we will calculate six surface areas.
P1=5x5=25 ( on the top)
P2=9x5=45 ( on the bottom)
P3= 5x5= 25 (left side)
P4=6,4x5=32 (rightside)
P5= (9+5)x5/2=70/2=35 ( front trapeze)
P6=P5=35 ( behided trapeze)
P= p1+p2+p3+p4+p5+p6=
25+45+25+32+35+35 =197
