(4x+6)(2x-5)
= 8x^2 - 20x + 12x - 30
= 8x^2 - 8x - 30
Answer:
19/24
Step-by-step explanation:
From the question we are informed that Lisle bought 3/8 pounds of red grapes and 5/12 pound of green grapes
✓3/8 pounds of red grapes and 5//12
✓First thing to do is to add the fractions
But we need " the least common denominator" because their denominator are not the same, we need to make it the same...
✓ The two denominator ( 8 and 12) are both factor of 24, therefore their "least common denominator" is 24.
✓To make 3/8 pounds of red grapes has a denominator of 24, we multiply both the denominator & numerator with factor of 3.
3/8 = (3×3)/(8×3)=9/24
✓To make 5/12 pounds of green grapes has a denominator of 24, we multiply both the denominator & numerator with factor of 2.
5/12= (5×2)/(12×2)= 10/24
✓ we can see they both have the same denominator, then we can now "add both denominators"
(9+10)=19
✓ Then place the addition of the denominators on the least common denominator.
= 19/24.
Therefore, he bought 19/24 of grapes
Answer:
3.934 = 3.634; hope this helps........
Step-by-step explanation:
Solve:
Multiply the numbers
5.62 ⋅ 0.7 = 2.68 ⋅ 1.35
3.934 = 2.68 ⋅ 1.35
Multiply the numbers
3.934 = 2.68 ⋅ 1.35
3.934 = 3.618
Result
3.934 = 3.618
The input is a contradiction: it has no solutions

Answer:
Y=10x+25
Step-by-step explanation:
Hey so let’s take the number of hours we go boating as “x” and the TOTAL cost of this whole trip as “y”.
So obviously y would equal everything else so we can write
Y=
Next, it says we rent a canoe for $10 an hour. That means we would have to multiply 10 and x to find the cost of the rent.
So
Y=10x
Finally, it says we paid a registration fee of $25. This 25 is not affected by the number of hours or anything else. It is a fixed amount so we can represent it as
Y=10x+25
Hope this helps!
