Answer:
x = 10
Step-by-step explanation:
2(1+5x)-3x=72
Distribute
2 + 10x -3x = 72
Combine like terms
2+7x=72
Subtract 2 from each side
2+7x-2 = 72-2
7x = 70
Divide by 7
7x/7 = 70/7
x = 10
Answer:
26. <u>c. 6 cm</u>
27. <u>c. 70 cm³</u>
Step-by-step explanation:
<u>Question 26</u>
- Volume = Length × Width × Height
- 360 = 10 × 6 × Width
- Width = 6 cm
- <u>c. 6 cm</u>
<u></u>
<u>Question 27</u>
- Volume = Length × Width × Height
- Volume = 7 × 5 × 2
- Volume = 70 cm³
- <u>c. 70 cm³</u>
<u></u>
<u>Question 28 (not entirely visible)</u>
(5,9) because vertex form is (x-h)^2+k and the vertex is (h,k) so it would be (5,9)
The answer is c). The reason why is that no matter what number you substitute for x in question c you can never get a negative number. Thus, you can never get a negative 8.
