Answer:
1926cm²
Step-by-step explanation:
Given
Dimension = 21cm by 18cn by 15cm
<em>The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:</em>
<em></em>

Where L, B and H are the dimensions.
So,





<em>Hence, 1926 cm² of fabrics are needed to cover all surfaces.</em>
Answer: see work below
Step-by-step explanation:
1) 3(2f + 4)
distribute the 3
= 6f + 12
2) 3(4t + 2)
distribute the 3
= 12t + 6
3) 7(6k -2v)
distribute the 7
= 42k - 14v
4) 5(2q - 9)
distribute the 5
= 10q - 45
(im not sure what the red mark is. if it's a negative than my answer would be opposite: -10q + 45)
5) 3(2e + 5t)
distribute the 3
= 6e + 15t
(im not sure what the red mark is. if it's a negative my answer would be opposite: -6e -15t)
6) 4(3r - 5)
distribute the 4
= 12r - 20
Answer:
d
Step-by-step explanation:
d is .04 percent plz mark branliest
Answer:
24km
Step-by-step explanation:
16/4 is 4 so you multiply that by 6 and you get 24. the equation is (16/4)*6
If this helps you consider making it brainliest as it helps me out.
2(x+4y) is the equivalent expression.
Let’s say x = 1 and y = 2
Then 2x + 8y would be 18
Same thing for 2(x+4y)
Hope this helps!
