Answer:
A5 is approximately 5.8 by 8.3 inches in size, and it's the closest in size to the U.S. paper size called the “half-letter” size, at 5.5 by 8.5 inches. But here's how all the A-series sizes break down: A0 paper is 841 by 1189 millimeters, approximately 33.1 by 46.8 inches.A5 measures 148 × 210 millimeters or 5.83 × 8.27 inches. In PostScript, its dimensions are rounded off to 420 × 595 points.A5148 x 210mm5.8 x 8.3 inch
Answer:
Step-by-step explanation:
-7x = x² + 12
Set equation to zero:
x² + 7x + 12 = 0
Quadratic formula:
x = [-7±√(7²-4·1·12)]/[2·1]
= [-7±√1]/2
= -3,-4
The zeros are -3 and -4
To find the area of this just add the units I believe which is 21
Hope this helps good luck. Not sure if this is 100% right my last year teacher was a sucky one
<span>arc length = circumference • [central angle (degrees) ÷ 360]
Solving this equation for circumference:
</span>
<span>circumference = arc length / (central angle / 360)
</span><span>circumference = 12 / (85/360)
</span>circumference = 12 / <span><span>0.2361111111
