Yes this is correct. if you do distribution and multiply 2 times x it's 2x. you then multiply 2 times 6 and this equals 12. add twelve and 8 and this equals 20. the answer 2x+20 is correct
Answer:
29.05 ft
Step-by-step explanation:
Using the concept of pythagoras theorem, here we have the base and hypotenuse given hence we need to find the third dimension, assuming the wall is perfectly straight and forms a right angle with the bsse of the ladder. Here,
and making a the subject of the formula then
and substituting 30 ft for c and 0.25*30=7.5 ft for b then
Answer/Step-by-step explanation:
4x - 7 = -2x + 12 (Given)
Add 2x to both sides
4x - 7 + 2x = -2x + 12 + 2x (Addition property of equality)
6x - 7 = 12 (Simplication)
Add 7 to both sides
6x - 7 + 7 = 12 + 7 (Addition property of equality)
6x = 19 (Simplification)
Divide both sides by 6
(Division property of equality)

Answer:
582 (C)
Step-by-step explanation:
The side closest to us (and the back too) is 9*9 + (15-9)*(15) = 81 + 90 = 171 *2 sides = 342
The top and bottom faces are: 15*4 = 60 * 2 sides = 120
The left side + right side = 15*4 * 2sides = 120
120+120+342 =
