Answer:
a) 2x + 1, 4x + 7
b) L = 19 cm, W = 7 cm, A = 133 cm^2
Step-by-step explanation:
8x^2 + 18x + 7
ax^2 + bx + c
ac = 8 * 7 = 56
56 = 4 * 14
8x^2 + 18x + 7 =
= 8x^2 + 14x + 4x + 7
= 2x(4x + 7) + 1(4x + 7)
= (2x + 1)(4x + 7)
a) 2x + 1, 4x + 7
b)
2(3) + 1 = 7
4(3) + 7 = 19
A = LW = 19(7) = 133
Answer:
2) 476.637
7) 2.2 and 2.20
8) 8.10 and 8.100
9) 9.5 and 9.500
10) 4.2 and 4.20
Step-by-step explanation:
2) First, solve 1/10 1/100, and 1/1000. That would be 0.1, 0.01, and 0.001.
Then, add all the numbers up. Do multiplication first. 4 x 100 = 400. Your answer would be 400 + 70 + 6 + 0.6 + 0.03 + 0.007. Add the big numbers. 476 + 0.637.
7) 2.2 and 2.20. It doesn't change the value no matter how many 0's you put.
8) 8.10 and 8.100
It doesn't change the value no matter how many 0's you put.
9) 9.5 and 9.500
It doesn't change the value no matter how many 0's you put.
10) 4.2 and 4.20
It doesn't change the value no matter how many 0's you put.

The article is 10 lbs...so 20 of them = (10 * 20) = 200 lbs
the box is 1/2 lb....so 20 of them = (1/2 * 20) = 10 lbs
the freight container is 15 lbs
for a total of : 200 + 10 + 15 = 225 lbs <==
If there are 196 refrigerators produced daily, that means that 8 are produced in an hour. subtract 8 and 3 and you get 5 refrigerators that are not defects. now multiply 5 by 24, about 120 refrigerators out of the 196 are not defects.
Answer:
Center: (-1,8)
Radius: 1
The graph is attached.
Step-by-step explanation:
The equation of the circle has the form:
Where (h,k) is the point of the center of the circle and r is the radius of the circle.
The equation given in the problem is
Therefore:
h=-1
k=8
Then, the center is (-1,8) and radius is 1.
You can graph the circle with its center at the (-1,8) and a radius of 1 as you can see in the figure attached.
