Two smaller triangle have areas of 75 m square and 12 m squared. find the ratio of their perimeters

Paul [167]

we know that two similar triangles will have ratio corresponding side is same.

ratio triangle 1 is 75m^2.

and triangle 2 is 12m^2.

$75:12=\frac{75}{12} =\frac{25}{4} .$

so we have ratio of area $25:4$ .

ratio of perimeter will be $\frac{25}{4} =\frac{50}{8} =\frac{25}{12}$ .

from these perimeter ratio also $\frac{25}{4} =25:4$ .

-(r+4) = -3 solve each expression plz explain step by step so i can understand

Ugo [173]

There’s an invisible 1 in front of the minus sign and an invisible 1 in front of the variable.

-1(r+4)=-3 —> -1 times 1r = -1r. -1 times 4 = -4
Multiply inside the parentheses.

-1r-4=-3

Now add 4 to both sides.

-1r-4=-3
+4=+4
-1r = 1
Now divide

R= -1
