<em>3(5+1) ÷ 3² = 3(6) ÷ </em><em>3</em><em>²</em>
<em>= 18 ÷ 3² = 18 ÷ 9 = 2</em>
Answer: A. 9x^2+2x-5
Step-by-step explanation: its just adding the two numbers from right to left so +3-8= -5 then -5x+7x=2x then 6x^2+3x^2= 9x^2 so putting them together equals 9x^2+2x-5
2:3, 2/3, or 2 to 3. You can write this ratio any of the three ways I listed.
Answer:
74 + 6x + 8 = 180
6x + 82 = 180
6x = 180 - 82
6x = 98
x = 98/6
x = 16.3
this answer is only correct
<em><u>when </u></em><em><u>angles</u></em><em><u> </u></em><em><u>in </u></em><em><u>linear</u></em><em><u> pair</u></em>
V = (Base Area)(height)
V = (side)^2 * (height)
144 = 4^2 * h
144 = 16*h
h = 144/16
h = 9 cm. [ANSWER]
