Triangle:
Area = 1/2*b*h
= (1/2)*3*4
= 3*2
= 6 m^2
7a.
1cm^3
Or, 1cm * 1cm * 1cm
Or, 10mm * 10 mm * 10 mm
Or, 1000 mm^3
7b.i)
10 cm^3
Or, 10cm * 1cm* 1cm
Or, 100mm * 10mm * 10mm
Or, 10000 mm^3
8.)
Volume = 50 cm^3
Base area= 5 cm^2
Now,
Volume = area * height
Or, 50 = 5 * height
Or, height = 50/5
Or, height = 10 cm
Plz mark this as the brainiest. :)
Answer:
<h3>a = 15</h3>
Step-by-step explanation:
5a - 5 - 15 = 3a + 6 + 4 <em>combine like terms</em>
5a + (-5 - 15) = 3a + (6 + 4)
5a - 20 = 3a + 10 <em>add 20 to both sides</em>
5a = 3a + 30 <em>subtract 3a from both sides</em>
2a = 30 <em>divide both sides by 2</em>
a = 15
