Answer:
-2x²-4x or -2x(x+2)
Step-by-step explanation:
(f+g)(x) means we are adding the values of f(x) and g(x):
f(x) = -2x²-9x
g(x) = 5x
(f+g)(x) = -2x²-9x+5x = -2x²-4x = -2x(x+2)

Find the area of the shaded region
helpp!!
Answer:
1. 116 m
2. 60 cm
Step-by-step explanation:
1. The total area is 12*10 m, or 120 m. The area of the non-shaded region is 7*2 m, or 14. Subtract 14 from 120 to get 116.
BTW the side 12 looks like it is less than the 10, the question is not lengthed properly, just saying
2. A bit trickier, divide the question into 2 parts, a triangle and rectangle.
The rectangle is 12*4 cm, or 48 cm, the triangle is 12 - 3 - 3 = 6 and 8 - 4 = 4
So we use 6 and 4. The area of a triangle is 1/2b * h, half of the base times the height, the base is 6 cm, and the height is 4 cm, 1/2(6) * 4 = 3*4 = 12 cm
48 + 12 = 60 cm

Answer:
240
Step-by-step explanation:
Answer:
240²
Step-by-step explanation:
Okay, so we can split this up into the triangle at the top, and the rectangle on the bottom, so:
4 x 20 ÷ 2 = 40
20 x 10 = 200
40 + 200 = 240
so the area of the shape is 240²

So Nelly gets £8 an hour for the first 15 hours, so you have to find the product of 8 and 15 which is £120. Then she gets an extra £10 for every extra hour, so we have tl subtract 15 hours from how many total she worked. To do that, we first have to add all of the hours together which would be 22 hours. Then we have to subtract the 15 which is 7 hours. However, the 5 hours on Saturday are going to pay double so we will calculate that afterwards. so 7 minus 5 is 2. Nelly gets paid £8 pounds for every hour so she gets £16 for 2 hours. Now, since are doubling £8 we get £16. So Nelly gets paid £16 an hour for the hours she worked on Saturday. 5 times 16 is £80. Now we add it all together. £120 + £16 + £80 = £216
Hope this helps :)

Based on the given condition we can formulate: 5/6 ÷ 1/8
=5/6 × 8
=5/3 × 4
= 20/3
=6.666≈7
Therefore, 7 whole enchiladas he can make with 5/6 jars of sauce.
