Answer:

Step-by-step explanation:
<u>Given:</u>
Mass = m = 1.76 g
Volume = v = 0.5 cm²
<u>Required:</u>
Density = ρ = ?
<u>Formula:</u>
ρ = m / v
<u>Solution:</u>
ρ = 1.76 / 0.5
ρ = 3.52 g/cm³

Here's an answer, with some big 'IF's attached. We can't be
sure of anything, because you never shared the picture of it
that was 'shown above'.
The area of a trapezoid is (1/2) (height) (base-1 + base-2).
Now, <u>IF</u> 'x' is one of the bases, and <u>IF</u> 'y' is the other one,
and <u>IF</u> 'h' is the height of the trapezoid, then
Area = (1/2) (6) (14 + 8)
= (3) (22) = <em>66 square units</em>.
But if any of them is not, then it isn't.

Answer
W=7
Explanation:
The formula for the perimeter for a rectangle is P = 2L + 2W
The formula for the area of a rectangle is A = LW
where L = length and W = width
P = 22 and A = 28
22 = 2L + 2W
28 = LW
Rewriting the 2nd equation L = 28/W
Substituting this into the first equation
22=2(28/W) + 2W
Reworking the equation to eliminate the denominator
22W = 2(28) + 2W2
22W = 56 + 2W2
and
2W2 - 22W + 56 = 0
Dividing by 2
W2 - 11W + 28 = 0
(W-7)(W-4)
Set each factor equal to 0 and solve each for 0
W = 4, W = 7
then W = 4

<2 + <5 = 180 this is a straight line
<2 + 150= 180
subtract 150 from each side
<2 = 30
<2 + <3 + <4 = 180 a triangle is 180 degrees
30 + <3 + 70 = 180
100 + <3 = 180
<3 = 80
