Answer:
x=2.600
Step-by-step explanation:
2x(x+4)+7+=(x+8)+ 2x(x+1)+12
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-> 2*x*(x+4)+7+-((x+8)+2*x*(x+1)+12)=0
-> ((2x•(x+4))+7)-(((x+8)+2x•(x+1))+12) = 0
-> (2x • (x + 4) + 7) - (2x2 + 3x + 20) = 0
-> 5x - 13 = 0
-> Add 13 to both sides of the equation :
5x = 13
Divide both sides of the equation by 5:
x = 13/5 = 2.600

Answer:
P'(7 , -11)
Step-by-step explanation:
what this tells us
(x,y) → ( x+3, y−2)
Is that the value of x of the new point is going to take (x + 3) with respect to the value of x of the other point.
Is that the value of y of the new point is going to take (y - 2) with respect to the value of y of the other point.
P (4,−9)
x = 4
y = -9
P'( x+3, y−2)
x + 3 =
4 + 3 = 7
y - 2 =
-9 - 2 = -11
P'(7 , -11)
No is the answer i believe
So 2e:3t 3t+15=1e:3e so
2e:3t
3t+15
1e:3t
1e:3t=2e:6t
so 2e:6e
2e:3t+15=2e:6t
15=3t
t=5
2+3=5 units
5 times 5=25
he made 25 samiches in all
check
e:t=10:15=2:3
15+15=30
10:30=1:3
checks
he made 25 sammiches origonaly
