Answer:
3.36
Step-by-step explanation:
47/14
3 5/14
5 divided 14 is 0.3571428571
0.3571428571 + 3 = 3.357142857
3.357142857
3.36
Answer:
1. 6 x^2 - 28 x + 30
2. (x-6) (x+3)
b cannot see
4a 20 x^3 - 10x^2 ft^3
b 160 ft^3
Step-by-step explanation:
1. (2x-6) * (3x-5) =
6x^2 -18x-10x+30
6 x^2 - 28 x + 30 excellent job
2. x^-3x-18
what numbers multiply together to give -18 and add together to give -3
-1* 18 = -18 -1+18 = 17
-2 * 9 = -18 - 2 + 9 = 7
-3 * 6 = 18 -3 + 6 = 3
-6 * 3 = -18 -6 + 3 = -3
(x-6) (x+3) excellent
I cannot check part b because it is cut off
4. V = l * w * h
V = (8x-4) * x * 2.5x
(8x-4) * 2.5x^2
20 x^3 - 10x^2
if x=2
V = 20 (2)^3 - 10 (2)^2
V = 20*8 - 10*4
V = 160 - 40
V = 120 ft^3
A rotation 270° counterclockwise about the origin is the same as rotation 90° clockwise about the origin and has a rule:
(x,y)→(y,-x).
Then:
- D(−2,4)→D'(4,2)
- E(4,7)→E'(7,-4)
- F(10,3)→F'(3,-10)
- G(8,0)→G'(0,-8)
Answer: the coordinates of vertices of quadrilateral D′E′F′G′ are D'(4,2), E'(7,-4), F'(3,-10), G'(0,-8).
Answer:
1.62,15/20,16.2%
Step-by-step explanation:
Answer:
Lets solve it
4x-3 <5
4x<5+3
4x<8
x<8/4
x<2
So yes, two is a solution
