Answer:
(4,-2)
Step-by-step explanation:
Start off by doing everything in the parenthesis which is everyone of them so 2x-1=-2 , your problem then should look like this:
-2(3x2-5x+2) carry the 2 over so multiply the 2 to everything so
(-6x-4+10x+2) add like numbers
10x+-6=4
-4+2=-2
(4,-2)
(r + 10)(r - 4)
To double check:
r * r is r^2
10 * r = 10r; -4 * r = -4r
Combine to get 6r.
-4 * 10 = -40

Answer:
x= 44 ounces y = 66 ounces
Step-by-step explanation:
Distribution would be an increase to find 80% salt.
Where we use 4/5 = 80 but use here 4/5.
We find 19/20 but just say 95 for solution B =
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
x + y = 110 y = 110 - x
(70x + 95y) = 4/5 x 110
70x + 95y = 88
70x + 95 y = 88
70x + 95 (88 - x) = 8800 make units equal or for start convert decimalization = same units as 2nd multiplied value.
70x + 8360 - 88x = 8800
-10x - 8360 - 8800 = y
-10x = 440
x = 44 ounces
y = 110- 44
y = 66 ounces
Answer:
Some other names that we use for rectangles are parallelograms, quadrilaterals, and polygons.
So, 3 different names.
Hope this helps!
