Answer:
330cm
Step-by-step explanation:
The formula to find the surface area of a rectangular prism is 2(lh+hw+lw)
(lh) in this formula is length times height
(hw) is height times width
(lw) is length times width
To find the answer to this problem lets make the height 3/5cm the width 10cm and the length 15cm
so now you would do (15*3/5) which is 9. This solve (lh)
then you would find (3/5*10) which is 6. This solves (hw)
and lastly you would find (15*10) which is 150. This solves (lw)
Now that you now the value of each one of these you replace it in the equation as so: 2(9+6+150)
now you solve the brackets which leaves us with 2(165)
now you multiply 2 with 165
and the answer is 330cm
Surface area = 330cm

<h2>
Answer: y = ¹⁸/₅
x - 8
</h2>
Step-by-step explanation:
For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:
The question gives us two points, (0, -8) and (5, 10), from which we can find the slope and later the equation of the line.
<u>Finding the Slope</u>
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (10 - (- 8)) ÷ (5 - 0)
= ¹⁸/₅
<u>Finding the Equation</u>
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - (-8) = ¹⁸/₅ (x - 0)
we could also transform this into the slope-intercept form ( y = mx + c)
since y - (-8) = ¹⁸/₅ (x - 0)
⇒ y + 8 = ¹⁸/₅ x
∴ y = ¹⁸/₅ x - 8

6x+3y = 12
Solving for x
3(2x+y)=12
2x+y=12/3
2x+y=4
2x=4-y
X=4-y/2
