⦁The areas of two similar triangles ABC and DEF are 100 cm2 and 144 cm2. If EF = 15 cmthen find the length of side BC.
ch4aika [34]

we know that


area larger triangle (DEF)=[scale factor]²*area smaller triangle (ABC)

solve for scale factor

scale factor=√[area larger triangle/area smaller triangle]

scale factor=√[144/100]------> scale factor=1.2


therefore

measure EF=scale factor *measure BC

solve for measure BC

measure BC=measure EF/scale factor-------> 15/1.2------> 12.5 cm


the answer is

measure BC is 12.5 cm

What is the solution to the following equation?
MrRa [10]
I believe the answer is 3.
If you would like me to show my work please reply saying so.
Sorry if I'm wrong, but I hope this helps.

4(3x - 6) +15 = 27
Distributive Property
12x + -24 + 15 = 27
Add the two constants (numbers without variables)
12x + -9 = 27
Because 9 is negative, add 9 to both sides.
12x = 36
Divide both sides by the coefficient (number with x)
x = 3
