First you need to multiple minus in second bracket, also in other side you need to multiple - 3 in bracket

7t - 2 + 3t - 1 =  - 3 + 9t \\  \\ 10t - 3 =  - 3 + 9t \\ 10t - 9t =  - 3 + 3 \\ t = 0

Alla [95]
We know that

a) find <span>the ratio of the perimeters 
</span><span>
the ratio of the perimeters is equal to the scale factor
</span>scale factor=26/6-----> 13/3
the answer Part a) is
the ratio of the perimeters is 13/3

b) find <span>the ratio of the areas of the larger figure to the smaller figure
we know that
area larger figure=[scale factor]</span>²*area smaller figure
scale factor²=area larger figure/area smaller figure

the ratio of the areas of the larger figure to the smaller figure is equal to scale factor squared
scale factor²=(13/3)²----> 169/9

the answer Part b) is
169/9

the complete answer is
13/3 and 169/9
