Answer:
<em>D. 5.385 grams per cm^2</em>
Step-by-step explanation:
Density can be found using the equation:
p = m/v
(p: density, m: mass, v: volume)
Plug in the information we know.
m = 70
v = 13
So
p = 70 / 13
p = density = 5.385
Answer:
<h3>x = 7</h3>
Step-by-step explanation:
The sum of the adjacent side of the trapezium is 180 degrees, Hence;
97 - 3x + 69+5x = 180
166 + 2x = 180
2x = 180 - 166
2x = 14
x = 14/2
x = 7
Hence the value of x is 7

We use long division to divide
There is no x term in x^2 -1 so we put 0x
x + 1
----------------------------
x^2+0x-1 x^3+ x^2 + x+ 2
x^3+0x^2-x
-----------------------------(subtract the bottom from top)
x^2 +2x + 2
x^2 +0x - 1
--------------------------------(subtract the bottom from top)
2x + 3
-----------------------------------------
Quotient : x+1
Remainder : 2x+3

Y - 3 = 1/2 (x + 4)
y - 3 = 1/2 x + 2
1/2x + 2 = y - 3
1/2x - y = -3 - 2
1/2x - y = -5 answer
