You would do 20-6 which = 14. + 1 =15. times 8= 120 then divide that by 1/2 = 240 if you do 120 divided by .5 in a calculator thats what you get. i hope that helps you
First, in order to know the surface area, you need to know the length and width as well, not just the hight.
Answer:
168 cm²
Explanation:
Lateral surface area of triangular prism: (perimeter of base) × height
Here given:
So, lateral surface area:
= (4 + 6 + 4) × 12
= 168 cm²
Answer:
(b)
Step-by-step explanation:
(-9/6) / (-3/2)
keep the first fraction, change division to multiplication, then flip the second fraction
-9/6 x 2/-3
multiply the numerators by each other and do the same with the denominators
-9x2 / 6x-3
-18 / -18
simplify
answer = 1 (negative divided by negative will always equal a positive)
