16 POINTS!! The solid in the diagram has a surface area of 18 units2. If a cube is added on the green face, what will the new su
rface area be? A) 20 units2 B) 21 units2 C) 22 units2 D) 23 units2
1 answer:
The complete question in the attached figure
Let
x------> length side of a cube
we have that
[surface area original]=18 units²
surface area original=x²*[number of faces]
number of faces=2*[4+4+1]-----> 18 faces
surface area original=x²*[18]
18=18*x²-------> x²=18/18---------> x=1 unit
<span>If a cube is added on the green face,the new surface area will be
</span>18+4*[area of one faces]-----> 18+4*1²----> 22 units²
the answer is
22 units²

Answer:
y = x
Step-by-step explanation:
slope-intercept form: y = mx + b
Given: slope(m) = , point (4, -3)
We already have the value of m, but we need to find the value of b. To do this, input the given values of the slope and the point into the equation:
-3 = (4) + b
Solve for b:
-3 = (4) + b
-3 = -3 + b
0 = b
The value of b is zero. We can now write the equation:
y = x + 0
y = x
The equation written in slope-intercept form is: y = x
