1) 9x + 2 = x + 5 ---> 9x + 2 = 6
subtracted X from one side but not the other
2) 3(x-4) + 5 = 12 ---> 3x + 4 + 5 = 12
didn't distribute correctly: 3(x-4)
multiplied the X by 3 but not the -4
Answer:
If there are 324 paving stones, it will cost $1539
Step-by-step explanation:
324 x 4.75 = 1539
The two triangles are similar, so will have a direct scale factor. We can find this by using the given measurements, 10÷8=1.25. So the scale factor from the smaller to the bigger triangle is 1.25. This means that 1.25×(x+6)=AE. We can solve this as we would with a regular linear equation:
1.25(x+6)=2x+6
1.25x+7.5=2x+6
1.5=0.75x
2=x
∴ AE is 2x+6=10

Answer:
Step-by-step explanation:
<u>Plot the points first:</u>
- Triangle GHJ: G(1,−6), H(2,−5), J(2,1)
- Triangle NOP: N(−6,1), O(−5,2)
Missing Point P is in quadrant 3and its coordinates are (-6, -5) as per symmetry with triangle GHJ.
