Answer:

Perimeter: 48mm

Area: 95mm

Step-by-step explanation:

Perimeter=2(l+w)

2((8x+3)+5)

-8x=2(3+5)

-8x=2(8)

-8x=16

x=2

2((8(2)+3)+5)= 48

So the perimeter is 48mm

Area=wl

l=19mm

w=5mm

19*5=95mm

So the area is 95mm

What is the solution of the equation x2 − 12x = 8?

Tanya [424]

Answer:

x = 12.63 or x= -0.63

Step-by-step explanation:

From my understanding the question is x² - 12x = 8

This will be solved through a quadratic equation formula.

Step 1: Form a quadratic equation

x² - 12x = 8

x² - 12x - 8 = 0

Step 2: Apply the quadratic formula

a = 1, b = -12, c = -8

x = -b±√b²-4ac

x = -(-12)±√(-12)²-4(1)(-8)

2(1)

Step 3: Find the value of x

x = 12±4√(11

x = 12+4√(11) or x = 12-4√(11)

2 2

x = 12.63 or x= -0.63

What is the unit rate of the data if two points are (0,0) and (1,4)

vlada-n [284]

ANSWER

$4$

EXPLANATION

The unit rate of the data represented by the straight line going through the points (0,0) and (1,4) is the slope of the this straight line.

We use the slope formula to determine the unit rate.

$m = \frac{y_2-y_1}{x_2-x_1}$

This implies that,

$m = \frac{4 - 0}{1 - 0}$

$m = \frac{4}{1} = 4$

Hence the unit rate is 4
