Answer:
Step-by-step explanation:
A)
f(s)=2s+25 and s(w)=25w
f(w)=2(25w)+25
f(w)=50w+25
B)
The ujits for the composite function are f=number of flowers and w=number of weeks.
C)
f(30)=50(30)+25
f(30)=1500+25
f(30)=1525
Hello from MrBillDoesMath!
Answer: B
Remark: It is customary to use x^2, not x2, to indicate the square of x.
Discussion:
(4x + 3) ^ 2= ( 4x)^2 + 2 * (4x)(3) + 3^2 =
16 x^2 + 24x + 9
Thank you,
MrB
Answer:
see explanation
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Summing the 3 angles and equating to 180 gives
2x + 3 + 4x + 2 + 2x - 1 = 180
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
∠A = 2x + 3 = (2 × 22) + 3 = 44 + 3 = 47°
∠B = 4x + 2 = (4 × 22) + 2 = 88 + 2 = 90°
∠C = 2x - 1 = (2 × 22) - 1 = 44 - 1 = 43°
