Answer:
9r³ + 2r⁴
Step-by-step explanation:
Step 1: Write expression
4r³ + 3r⁴ - (r⁴ - 5r³)
Step 2: Distribute negative
4r³ + 3r⁴ - r⁴ + 5r³
Step 3: Combine like terms
9r³ + 2r⁴
CHECK THE ATTACHED FIQURE FOR THE BRIDGE
Answer:
60 ft
Step-by-step explanation:
From the question we know that triangles ABC and EDC are in a 1:1 with this given ratio it implies that
triangles ABC and EDC are congruent then we can say
side EC = side AC
3x + 9 = 5x - 5
Then we can simplify to know value of x
3x + 14= 5x
2x = 14
x = 7
But we know that AC= 5x - 5 , then substitute value of x into it
AC = 5x + 5 = 5(7) - 5
= 35 - 5
AC= 30 ft
Also EC= 3x + 9 then substitute value of x into it
EC = 3x + 9 = 3(7) + 9
= 21 + 9
EC= 30 ft
Then the the distance between the top and bottom of the bridge, in feet, = EC+AC
= 30 + 30 = 60 ft
Okay dso if she got 15 points for 12 days then you would multiply them (or just add 15+15+15+15 and so on but multiplying is easier) then you are going to add 55 because of the thirteenth day.
15(12)=180
180+55=235 is how many you have.
now you are going to subtract 500 from that number to see how many more you need. :)
