Answer:
x= 15/7
Step-by-step explanation:
X = -1/2 (negative)
y = - 1.8 (negative)
so It's in Quadrant 3
3x^2+12x+15=0
Then divide by 3 to get the x by itself.
x^2+4x+5=0
Factor to (x+5) (x-1) and solve for the two values of x.
Answer:
Step-by-step explanation: The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
Algebraic expression: 100+8n=x
cost if 20 people attend: 100+8*20 = 100+160
cost if 50 people attend: 100+8*50 = 100+400
New cost of the party when 'n' people attend:100+250+8n=x
Cost for party with 40 people and dj:100+250+n(8+2)=x
