Answer:

$188\sqrt{2}-8\sqrt{5}$ feet

Step-by-step explanation:

Well the perimeter is the sum of all sides that means

P= lenght + width + lenght + width

P=2(lenght + width)

$P=2(2\sqrt{8}+3\sqrt{5}+45\sqrt{8}-7\sqrt{5} )\\\\P=2((2+45)\sqrt{8}+(3-7)\sqrt{5})\\\\P=2(47\sqrt{8}-4\sqrt{5})\\\\P=2(94\sqrt{2}-4\sqrt{5})\\\\P=188\sqrt{2}-8\sqrt{5}$

Write as a product: 25a2−0.01b10

Yakvenalex [24]

Answer:

We conclude that:

$25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)$

Step-by-step explanation:

Given the expression

$25a^2-0.01b^{10}$

Rewrite $25a^2-0.01b^{10}$ as $\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2$

$25a^2-0.01b^{10}=\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2$

Apply difference of two squares formulas:

$x^2-y^2=\left(x+y\right)\left(x-y\right)$

$\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2=\left(5a+\sqrt{0.01}b^5\right)\left(5a-\sqrt{0.01}b^5\right)$

$=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)$ ∵ $\sqrt{0.01}=0.1$ ,

Therefore, we conclude that:

$25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)$

Mr. Jackson has received two salary offers at two different companies. Company A pays $40,000 per year with an increase of $2,00

NISA [10]

Answer:

Option B

He will earn $2,000 more with Company B

Step-by-step explanation:

<u>Company A</u>

First year-40,000

Second year=40000+2000=42000

Third year=42000+2000=44000

Fourth year=44000+2000=46000

Fifth year=46000+2000=48000

<u>Company B</u>

First year=30000

Second year=30000+5000=35000

Third year=35000+5000=40000

Fourth year=40000+5000=45000

Fifth year=45000+5000=50000

Difference after five years is 50000-48000=2000

Therefore, company B would have given him $2000 more than company company A

AC = c/3 Bd = 4 - c

Pepsi [2]

The diagonals of a rectangle are congruent
meaning AC and BD are congruent
c/3 = 4-c
multiply both sides by 3
c = 12 -3c
add 3c to both sides
4c = 12
divide both sides by 4
c = 3

So the diagonals are
AB = c/3 = (3)/3 = 1
BD = 4-c = 4- (3) = 1

Hope this helps
