Answer:
32+6w= total number of shows Jonah has recorded
Step-by-step explanation:
32 shows were already recorded so you just have to add 6 times the amount of weeks to get total amount of shows recorded.

Step-by-step explanation:
The quadratic formula is
-b ± sqrt(b^2 -4ac)
----------------------------
2a
3x^2 =2x-1
Lets get the equation in proper form
3x^2 -2x+1 = 2x-1-2x+1
3x^2 -2x+1 =0
a=3 b=-2 c=1
Lets substitute what we know
2 ± sqrt((-2)^2 -4(3)(1))
----------------------------
2(2)
-2 ± sqrt(4-12)
----------------------------
2(2)
-2 ± sqrt(-8)
----------------------------
4
No real solutions
The quadratic formula is
-b ± sqrt(b^2 -4ac)
----------------------------
2a
2x^2 -10= 7x
Lets get the equation in proper form
2x^2 -7x-10 = 7-7x
2x^2 -7x-10 =0
a=2 b=-7 c=-10
Lets substitute what we know, we are only looking for what is inside the radical
(b^2 -4ac)
((-7)^2 -4(2)(-10))
(49 +80)

Answer:
(a) 156 cm²
Step-by-step explanation:
The total surface area of the 12 blocks can be computed by first finding the surface area of one block. That result can then be multiplied by 12. The area of one rectangular prism is given by the formula ...
A = 2(LW +H(L +W))
A = 2(4·1 +1/2(4+1)) = 2(4 +5/2) = 13 . . . cm²
The area of 12 such prisms will be ...
12 × (13 cm²) = 156 cm²
Victor needs 156 cm² of fabric to cover 12 blocks.

<em>Additional comment</em>
This problem offers an opportunity to exercise your number sense. The area of the largest surface of one block is (4 cm)×(1 cm) = 4 cm². 12 of these surfaces will have an area of 48 cm². This is only part of the total area, so the only reasonable choice among those offered is 156 cm².
