Please help!! Please give step by step so i can understand
miss Akunina [59]

Answer:

p = - 14

Step-by-step explanation:

Using the rules of exponents

a^{m} ÷ a^{n} = a^{(m-n)}

(a^{m}) ^{n} = a^{mn}

Note 81 = 9² and 729 = 9³

Given

(81)^{-4} ÷ (729)^{2-p}

= (9^{2}) ^{-4} ÷ (9^{3}) ^{2-p}

= 9^{-8} ÷ 9^{6-3p}

= 9^{-8-(6-3p)}

= 9^{-8-6+3p}

= 9^{3p-14}

Thus

9^{3p-14} = 9^{4p}

Since bases on both sides are equal then equate the exponents

4p = 3p - 14 ( subtract 3p from both sides )

p = - 14

if a rectangle has an area of 30 square meters and a perimeter of 34 meters . what is the dimensions of the rectangle?
timama [110]
P=2(L+W)  and P=34 so

2(L+W)=34

L+W=17 so we can say

L=17-W

A=LW using L from above

A=(17-W)W

A=17W-W^2 and A=30 so

30=17W-W^2

W^2-17W+30=0

W^2-2W-15W+30=0

W(W-2)-15(W-2)=0

(W-15)(W-2)=0

So the dimensions of the rectangle are 15 meters by 2 meters.
