<span>.09X+.08(7,000-X)=588
.09X+560-.08X=588
.01X=588-560
.01X=28
X=28/.01

X=2,800 AMOUNT INVESTED @ 9%.
7,000-2,800=4,200 AMOUNT INVESTED @ 8%
PROOF:
.09*2,800+.08*4,200=588
252+336=588
588=588</span>

ANSWER

EXPLANATION

We want to simplify:

(2\sqrt{5}+3)(\sqrt{5}-1)

Recall the distributive property;

(a+b)(c+d)=a(c+d)+b(c+d)

We apply this property to get,

2\sqrt{5}(\sqrt{5}-1) + 3(\sqrt{5}-1)

We expand to get,

2 \times 5-2 \sqrt{5} + 3\sqrt{5}-3

This simplifies to,

10 + \sqrt{5}-3

The simplest form of the given expression is:

7 +  \sqrt{5}

The endpoints of WX are W(2,-7) and X(5,-4). What is the length of WX?
ss7ja [257]

Answer:

<h2>WX = 3√2 units </h2>

Step-by-step explanation:

Using the formula for calculating the distance between two points to calculate the length of WX.

D = √(y₂-y₁)²+(x₂-x₁)²

Given the endpoints W(2,-7) and X(5,-4), x₁ = 2, y₁ = -7, x₂ = 5 and y₂ = -4

Substituting this values into the formula to get the length of WX will give;

WX = √(-4-(-7))²+(5-2)²

WX = √(-4+7)²+3²

WX = √3²+3²

WX = √18

WX = √2*9

WX = 3√2 units

Hence the length of WX is 3√2 units.
