Things we know: every pound of cherries cost four dollars.
We don't know how much the mother got and it is represented by the variable 'r'. But we do know how many pounds the dad got. He got two pounds.
We know the total cost the mom had to pay which is 4 * r and the amount the dad paid is 4 * 2 or 8.
Now we want to make an algebraic expression that represents how much more the mother paid than the father.
Final answer:
8 - (4 * r)
Hope this helps!
Answer:
160 u^3
Step-by-step explanation:
For the sake of ease, I will split this prism into 2 prisms. One prism will be 2x4x5 while the second one will be 4x5x6. The volume of the prism will be the sum of the volume of both prisms.
Prism A: Volume would be lwh or 2*4*5=40
Prism B: Volume would also be lwh which is 4*5*6=120
40+120=160
The volume is 160 units^3
Hope this is correct and helps!
hello : <span>
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x1,2 =
(-b±√Δ)/2a</span></span>
factoring :
<span>ax²+bx+c = a(x-x1)(x-x2)
2 ) Δ = 0 : one solution : x1 = x2 = -b/2a</span>
factoring :
<span>ax²+bx+c = a(x-x1)²
3 ) Δ < 0 : no reals solutions... no </span>
<span>factoring </span>
uh i'm not sure i think its 2,also im having a terrible day so thank you :3
