Answer:
AD = 4.5
Step-by-step explanation:
Since the two bases of the two given triangles are parallel the triangles are similar.
Triangle BDE is similar to Triangle BAC
From this the following proportion can be set up.
BE / BC = BD/BA
BE = 8
BC = 8+12 = 20
BD = 3
BA = 3 + x where x = DA
8/20 = 3/(3+x) Cross Multiply
8(3 + x) = 3 * 20 Remove the brackets on the left. Combine Right
24 + 8x = 60 Subtract 24 from both sides
8x = 60 - 24 Combine the right
8x = 36 Divide by 8
x = 36/8
x = 4.5
But x = AD
Answer:
Step-by-step explanation:
Multiply: -4 and 5 which then equals X
Add Exponents: and then which finally equals to the answer,
Answer:
the building strong enough to withstand the denali quake
Step-by-step explanation:
the building strong enough to withstand the denali quake
Step-by-step explanation:
denali quake 6.7 x 70 = 469
the building in denali should be strong enough to withstand an earthquake of that magnitude
rat island quake 7.8 x 30 = 234
the building in the rat islands should be strong enough to withstand an earthquake of that magnitude :)

Answer:
Combining like terms is just that, combining numbers in an equation that have the same property. examples would be constants or numbers with the same exponent.
Properties of exponents are when you multiply, add, subtract, or divide exponents.
