8x - 2x(x+1) = 2(3x-1)
First, expand to remove parenthesis. / Your problem should look like:
8x - 2x - 2 = 6x - 2
Second, subtract 8x - 2x -2 to get 6x - 2. / Your problem should look like:
6x - 2 = 6x - 2
Third, both sides are equal, so there are infinite solutions. The equation is always true, meaning identity
Answer: Infinite solutions

Answer:
Step-by-step explanation:
Accessories: x
Bike: 4x
Total1: 5x
Total2: 140 dollars.
x + 4x = 140 dollars
5x = 140
x = 28
Accessories: 28
Bike: 112
Im not good in math and this is my first question, my best guess is D
I will investigate tommorow this problem a little bit more... <3
I dont know if you know this, but there are 3 different 3's. So how can we figure out the question if we don't know which one is underlined?
The product is negative 81 t squared + 16 ⇒ 2nd answer
Step-by-step explanation:
The product of two binomials (ax + b)(cx + d), where a, b, c, and d are constant
- Multiply (ax) by (cx) ⇒ 1st × 1st
- Multiply (ax) by (d) and (b) by (cx) ⇒ ext-reams and nears
- Add the two products ⇒ like terms
- Multiply (b) by (d) ⇒ 2nd × 2nd
Let us find the product of (9 t - 4) and (-9 t - 4)
Multiply the 1st two terms
∵ (9 t)(-9 t) = -81 t²
Multiply the ext-reams
∵ (9 t)(-4) = -36 t
Multiply the nears
∵ (-4)(-9 t) = 36 t
Add the like terms
∵ -36 t + 36 t = 0
Multiply the 2nd two terms
∵ (-4)(-4) = 16
Write the answer
∴ (9 t - 4)(-9 t - 4) = -81 t² + 0 + 16
∴ (9 t - 4)(-9 t - 4) = -81 t² + 16
The product is -81 t² + 16
