Answer:
tiles
Step-by-step explanation:
there are many ways to solve this soo...
1. convert to centimetres (there are 100 centimetres in 1 metre)
2. the square tiles area = 
2. find the large area (4.8m x 3.8m or 480cm x 380cm)
2. find the two smaller areas (1.2m x 1.8m or 120cm x 180cm)
3. add to find total area
4. find how many tiles are needed
tiles
Answer: It's the second option
Step-by-step explanation:
6.4 is the answer you are looking for! Hope that helps :))
24=3r/4
Multiply both sides by 4
24=(3r)/4
(24)*(4)=(3r/4)*(4)
96=3r
Flip the equation
3r=96
Divide both sides by 3
3r/3=96/3
r=32
Now lets check if the answer is good
24=3(32)/4
24= 96/4
24=24
You see , the answer is good .
I hope that's help ! Let me know .
Let the numbers be x and y. Then xy = -30 and x+y = -3.
Solve xy = -30 for y: y = -30/x
subst. -30/x for y in x+y= -3: x - 30/x = -3
Multiply all 3 terms by x: x^2 - 30 = -3x, so x^2 + 3x - 10 = 0
Solve this quadratic equation for x. x: {-5, 2}
If x = -5, then x+y = -3 becomes -5 + y = -3, and y = 2.
You should check to determine whether x=2 is also correct. If it is, what is the corresponding y value?
