First, we get the area of each tile: (100 cm = 1m)
.20 m* .15 m = 0.03m^2
Then, we solve for the total area of the wall:
5m*3m= 15m^2
Then we divide
15/0.03 = 500 tiles
Answer:
Step-by-step explanation:
let x be the number
2(x+8)=-4x+4
2x+16=-4x+4
6x=-12
x=-2
Y=2/3x
The y-intercept is zero, and the slope is 2/3
30). 247000 x 10^0
31). 0.00065
Answer:
x^2 - 3x - 30
Step-by-step explanation:
step 1: -9 + -1 = -10
-3 + -3 = -6
-1 + -9 = -10
1 + 9 = 10
3 + 3 = 6
9 + 1 = 10
No two factors can be found
Trinomial can not be factored
step 2: ((3x2 + 5x) - 12) - 2 • (x2 + 4x + 9)
step 3: -30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
so the answer is x^2-3x-30
