x-intercept:
y-intercept:
Step-by-step explanation:
To find the x-intercept, substitute in for
and solve for
.
Simplify 2(0):
Subtract 0 - 3 = -3:
Subtract 7 from both sides:
Simplify:
Divide both sides by -4
To find the y-intercept, substitute in for
and solve for
.
Switch sides:
Simplify -4(0):
Add 3 to both sides:
Simplify:
Divide both sides by 2:
Answer:
cm²
Step-by-step explanation:
Surface area of the composite figure = Surface area of the lateral surfaces of the given pyramids
Lateral surface area of a square pyramid = 4
Therefore, lateral surface area of the pyramid
=
Now lateral surface area of the composite figure = 2(lateral surface area of two pyramids)
=
Therefore, Expression for the surface area of the given composite figure is,
cm²
