Answer:

(x + 3) cm.

Step-by-step explanation:

Area = 2x^2 + 8x + 6

= (2x + 2)(x + 3)

The width = area / length

= (2x + 2) (x + 3) / (2x + 2)

= x + 3 cm.

(7, 1) and (x, 4); m = 3/4 missing value 50 POINTS

Sever21 [200]

Answer:

x = 11

Step-by-step explanation:

4 - 1 / x - 7 (simplify)

3 / x - 7 = 3/4 (multiply by x - 7)

3 = 3/4 (x - 7)

3 = 3/4x - 5.25 (add 5.25 to both sides)

8.25 = 3/4x (divide both sides by 8.25)

x = 11

sub into the formula to check:

4-1 / 11 - 7

3 / 4

WZ and XR are diameters of circle C. The diagram is not drawn to scale. What is the measure of ZWX?

Inessa05 [86]

Answer:

Measure of arc ZWX is 230°.

Step-by-step explanation:

Given:

arc WX = 50°

Now

The diameter divide a circle into two equal parts

$arc\ ZWX=arc\ ZRW+arc\ WX$

Since WZ is diameter of the circle.

$arc\ ZRW=180\°$

substituting in above equation we get

$arc\ ZWX=180\°+50\°=230\°$

Hence Measure of arc ZWX is 230°.
