Answer:
-4x(5x-3)
Step-by-step explanation:
-20x^2 - 12x
-20x^2 = -4*5*x*x = -2*2*5*x*x
-12x = -4*3*x = -2*2*3*x
The common terms are -2*2*x = -4x. Whats left goes inside the parentheses
-4x(5x-3)
The answer is 50, im surprised no one has answered yet
Answer:
2500 ft²
Step-by-step explanation:
The missing area at lower right in the diagram has dimensions...
(4-2 1/4) by (3 - 1 3/4) by (1 1/4)
Then area of that "Missing" space is (1.75)(1.25)= 2.1875 . . . . square inches. The area of the enclosing rectangle is ... (4 in) (3 in) = 12 square inches the area in the diagram representing the store is... 12 in² -2.1875 in² = 9.8125 in²
_
Each square inch on that diagram represents an actual area of (1 in)×(1 in) → (16 ft)×(16 ft) = 265 ft²
Then the actual store area is....
9.8125(256 ft²) = 2512 ft²
Rounded to the nearest 50 ft², this is 2500 ft².
Answer:
B produced 20000 panels
Step-by-step explanation:
Plant A produced 5000 fewer panels than Plant B did
A = B - 5000 eq1
Two percent of the panels from Plant A and 4% of the panels from Plant B were defective:
0.02A + 0.04B = 1100 eq2
Solving the two equations:
Put value of A from 1 in 2
0.02 (B - 5000) + 0.04B = 1100
0.06B - 100=1100
0.06B = 1200
B = 20000
C - (7,0) because 3x7= 21 add 4x0 = 0 which then equals 21 :)
