Answer:
8x^2-8.76x+2.92
Step-by-step explanation:
Factor using FOIL and then simplify
8/1 + (x-1)/(x+4)
You need the same common denominator (bottom number) to be able to add together so multiply 8 by (x+4) to both bottom and top
8 (x+4)/(x+4) + (x-1)/(x+4)
Add
8 (x+4)+(x-1)/ (x+4)
Distribute the 8 to (x+4)
8x+32+x-1 / x+4
Simplify
9x+31/x+4

Step-by-step explanation:
In isoceles triangle two sides are equal and two angles are equal.
Then,
∠R = ∠T = (5x-40)°
Then,
∠RTS + ∠STU = 180° (bcoz it lies on a straight line)
(5x-40) ° + 5x = 180°
10x = 220°
x = 22°
Therefore,
Option A is correct✔
The product always has two more zeros of two less decimal places
Answer:
Mark spent 13 dollars on supplies for the dance. His goal is to make 20 dollars. How much worth of tickets does he need to sell to make his goal.
Step-by-step explanation:
To find this, we know we need to subtract 13 from something, in this case ticket sales. That number must be larger than 20, which in this case is the profits.
