Answer:
-16x+3y
Step-by-step explanation:
(-6x)+(-10x)=-16x ,. (9y)+(-6y)=3y ,. so the answer is -16x+3y
Answer:
Here are the formulas
Cube/Rectangular Prism:
Volume = Length*width*height
Surface area = 2(wl+hl+hw)
Lateral area= Area of vertical faces
Base area = length*width
Regular hexagonal prism:
Volume : (3sqrt3/2)*a^2*h
Surface Area = 6ah+3sqrt(3)a^2
lateral area: 6ah
base area = 3sqrt(3)s^2/2
Triangular prism
Volume: The volume of a triangular prism can be found by multiplying the base times the height.
Surface area: A triangular prism has three rectangular sides and two triangular faces. To find the area of the rectangular sides, use the formula A = lw, where A = area, l = length, and h = height. To find the area of the triangular faces, use the formula A = 1/2bh, where A = area, b = base, and h = height.
Etc.
Use FOIL: <em>(a + b)(c + d) = ac + ad + bc + bd</em>
(2s - 2)(4s + 3)
= (2s)(4s) + (2s)(3) + (-2)(4s) + (-2)(3)
= 8s² + 6s - 8s - 6
<h3>= 8s² - 2s - 6</h3>
