Answer:
Step-by-step explanation:
<u>Perimeter is:</u>
- P = 40 cm
- and
- P = 2x - 4 + 5x - 13 + x + 9 = 8x - 8
<u>Comparing the value:</u>
- 8x - 8 = 40
- 8x = 48
- x = 8 cm
<u>Are formula:</u>
<u>Replacing values:</u>
- A = 1/2(x + 9)(2x - 4)
- A = 1/2(8 + 9)(2*8 - 4) = 1/2*17*12 = 102 cm²
Answer:
x = 11
Step-by-step explanation:
Given :
AB = x + 5
BC = 2(x - 3)
AB = BC
AB = BC
x + 5 = 2(x - 3)
x + 5 = 2x - 6
5 + 6 = 2x - x
11 = x
x = 11
happy to help :)
You simplify the fraction by dividing 2 to the nominator and the denominator. So 24/2=12, 8/2=4, 6/2=3. You can only divide a root with a root number so in this case the root three doesn't get affected
The probability of not getting an s or a blank is 94/100.
this is because there are 94 chances to get something other than those 6 tiles.
