Answer:
5236
Step-by-step explanation:
let x=43
f(43)=3(43)^2-5
f(43)=3(1749)-5
f(43)=5241-5
f(43)=5236
Answer:
∠ACB= 57°
AB= 8.80 units (3 s.f.)

Answer:
Step-by-step explanation:
L = 3*w + 1 Given
P = 2*(L + w) Formula for Perimeter. Substitute for L
P = 2*(3w + 1 + w) Combine
P = 2*(4w + 1)
P = 58 Given
58 = 8w + 2 Remove the brackets
58 - 2 = 8w Subtract 2
56 = 8*w Divide by 8
56/8 = w
7 = w
================
Find L
L = 3*w + 1
L = 3*7 + 1
L = 22
================
Check
2L + 2W = 58
2*22 + 2*7 =? 58
44 + 14 = ? 58
58 = 58
The answer checks.
This is a division problem:
Each box holds 20 bags.
800 bags / 20 bags per box = # of boxes
40 boxes are needed.
Convert to an equation:
50^2=2+25^2=2*5=10
Simplify:
2500=625=10=10
What is wrong is that 2500 does not equal 625 which does not equal 10.
