Answer:
75 square inches
Step-by-step explanation:
Area of a Triangle = 1/2 × Base × Height
From the above question:
Base = 30 Inches
Height = 5 inches
Hence:
Area = 1/2 × 30 in × 5 in
Area = 75 square inches
Therefore, the area of one of the triangular pieces of wood that she needs to build the ramp is 75 square inches
Add all sides.
5x+2+3x+8+4x-1
Combine like terms
12x+9
Subtract nine to get it on the other side of the equal sign
12x= -9
Divide by twelve
x=-9/12
Simplify
x=-3/4
Plug in x.
Answer:
Step-by-step explanation:
6.8/3 is the scale factor
1.35*(6.8/3)=3.06
1.8*(6.8/3)=4.08
3.75*(6.8/3)=8.5
8.5-8.35=0.15
3.4-3.06=0.34
since C is closer to the right proportion, if there is no option D, it should be the 2 answer you choose
Option B is definetly right, but what about another option, is there an option D?
First, you can multiply the numbers to the parenthesis:
5(4c-2d) = 20c - 10d
and
-6(d-3c) = -6d + 18c
now you have:
20c - 10d + 2d - 6d + 18c = (20c + 18c) + ( -10d + 2d - 6d ) = 38c - 14d and that is the simplest form :))))
I hope this is helpful
have a nice day
