Answer:

2. $(x - 4)^2 = 23$

Step-by-step explanation:

$x^2 - 8x - 7 = 0$

$x^2 - 8x ~~~~~ = 7$

$x^2 - 8x + 16 = 7 + 16$

$(x - 4)^2 = 23$

Which point is 5 units from (1, –3) on a coordinate plane? A. (–8, 6) B. (6, –3) C. (–3, –6) D. (1, –2)

Rudiy27

Because $\sqrt{ (-3-1)^{2} + (-6+3)^{2} } = \sqrt{ (-4)^{2}+ (-3)^{2} } = 
 \sqrt{16+9} = \sqrt{25} = 5 units;$ , the point is C(-3;-6).

What are the roots of the equation x 2-10x+21=0

horrorfan [7]

So factoring this would be:
(x-7)(x-3)
so the solution set is
{7, 3}
I'm not sure if this is what you were asking, if it wasn't, I'll edit it.

A farmer wishes to enclose a rectangular pasture with 1200 ft of fence. He needs to divide this rectangle into two smaller recta

Minchanka [31]

Answer: $60,000 ft^2$

Step-by-step explanation:

Given

total of 1200 ft of fence is available

Suppose rectangular pasture has following dimension as shown in figure.

total perimeter

$P=4a+3b$

$1200=4a+3b$

$4a=1200-3b$

$a=300-\frac{3}{4}b$

Area of rectangle is

$A=2a\times b$

$A=2(300-\frac{3}{4}b)b$

$A=2[300 b-\frac{3}{4}b^2]$

For maximum area, differentiate A w.r.t b

$\frac{\mathrm{d} A}{\mathrm{d} b}=300-\frac{3}{2}b=0$

$300=\frac{3}{2}b$

$b=200 ft$

so $a=300-150=150\ ft$

so area is

$A=2\times 150\times 200$

$A=60,000 ft^2$
