Answer:

202.5cm^2

Step-by-step explanation:

P=2l+2w

63=2(9)+2w

63=18+2w

63-18=2w

45=2w

divide both sides by 2

22.5=w

check:

P=2(9)+2(22.5)

=18+45

=63

Area=l×w

=22.5×9

=202.5cm²

Answer:

A = 202.5 cm²

Step-by-step explanation:

P = 63 = 2×9 + 2w

2w = 63 - 18

2w = 45

w = 22.5 cm

A = w×l = 9×22.5 = 202.5 cm²

Solve for t if p≠q (t+p)/q - q/p = (t-q)/p + p/q

german

Answer:

.. q T 0 = (q/p)a (q/p)a − (q/p)T−10 if p ≠ q and qT0 = 1 − T0/a if p = q = 1/2.

Step-by-step explanation:

Suppose that there are two different solutions, p and q, in [a, b]. Thus p =g(p) q =g(q) p ≠ q The function g(x) satisfies the hypotheses of the mean-value ... that g(p) –g(q) = (p – q) g׳(t) Because g(p) =p and g(q) = q, the left side of Eq. (1-3) may...

Prove that 3:8 is equivalent to 12:32.

ANEK [815]

3:8 can also be written as 3/8

12:32 can also be written as 12/32

 $\frac{12}{32} = \frac{3\times 4}{8\times 4} = \frac{3}{8}$

So thus 3:8 is equivalent to 12:32
