Answer:
f(-3)=-19
Step-by-step explanation:
-3 REPLACES THE x
Answer:
2172 is the total cost
Cost for tiles: 1800
cost of paint: 372
Find the surface area of the wall without floor:(for cost of paint)
40 x 15 + 40x3x2 + 15x3x2 = 600 + 240 + 90 = 930
Cost: 930/25 x 10 = 372
Find area of floor:(to find cost of tiles)
40 x 15 = 600m^2
cost: 600 x 3 = 1800pounds
add them if needed
Hope this helps
Good Luck
U is 50 because supplementary 180-130=50
And so knowing that now
50+65+x=180 (because all triangles are equal to 180)
Add 50 and 65
115 +x=180
Subtract 115 on both sides
X=65
The answer is A
Answer:
(a+b)(a-b)
a(a - b) + b (a - b)
= a^2 - ab + ab - b^2
=a^2 - b^2
Step-by-step explanation:
- distribute a(a-b)
- distribute b(a-b)
- add like-terms
