Answer:
x=2
Step-by-step explanation:
Answer:(4)
Step-by-step explanation:
1/2=x/8 cross multiply and you come up with 8 divided by 2 = 4
Step-by-step explanation:
<em>(-2)-(+15)=(-17)</em>
<em>the</em><em> </em><em>diffe</em><em>rence</em><em> </em><em>between</em><em> </em><em>those</em><em> </em><em>two</em><em> </em><em>temp</em><em>erature</em><em> </em><em>s</em><em> </em><em>is</em><em> </em><em>(</em><em>-</em><em>1</em><em>7</em><em>)</em>
2(6*8)=96
2(6*3)=36
2(8*3)=48
96+36+48= 180 sq. in.
(The above is the answer to #2).I shouldn't give the answer to all of them, but I can explain how to do it. In order to calculate surface area, you need to find the area for all sides of the shape. For example, #2 has six sides, so you need to find the area for all six of those sides. There are two sides that are 8 x 3, two sides that are 6 x 8, and two sides that are 6 x 3. Therefore, your equation would be 2(8x3) + 2(6x3) + 2(6x8). From that you get 48+36+96 = 180 square inches (sq. in.)
