Answer:
8
Step-by-step explanation:
Sides AB and AC are equal
So,
3x - 5 = 7
+ 5 on both sides
3x = 12
divide both sides by 3
x = 4
Now take the 2x and plug in x for 4.
2(4) = 8
Final answer is 8.
Answer:
3 1/6
Step-by-step explanation:
2 1/2 + 2/3 = 2 3/6 + 4/6. add 3 and 4, you get 2 7/6. simplify by taking 6 from 7 and add 1 to 2. that leaves you with the answer
Multiply both sides by -3 to get rid of the negative and the fraction.
X - 3 = 21
Move the constants over to isolate the variable
X = 24
Answer:
Option A
Step-by-step explanation:
Area of the composite figure = Area of ΔABH + Area of BCGH + Area of ΔDEF
Area of ΔABH = 
= 
= 9 in²
Area of the trapezoid = 
= 
= 25 in²
Area of ΔDEF = 
= 24 in²
Therefore, area of the given figure = 9 + 25 + 24
= 58 in²
Option A will be the correct option.
