The height of a triangle is 12 centimeters more than its base. The area of the triangle is 189 square centimeters Find the base
telo118 [61]

Answer:

C

Step-by-step explanation:

the area of a triangle is

baseline × height / 2

so, we know in our case

b(b+12) = 189 cm²

b² + 12b - 189 = 0

let's try to solve this by completing the square.

that means we try to find the expression

(b + k)² + c

that is equal to

b² + 12b - 189

(b + k)² + c = b² + 2kb + k² + c = b² + 12b - 189

so,

2k = 12

k = 6

and then

k² + c = -189

6² + c = -189

36 + c = -189

c = -225

(b + 6)² - 225 = 0

(b + 6)² = 225

b + 6 = 15

b = 9

so, the baseline b = 9 cm.

the height b+12 = 9+12 = 21 cm.

Tom and Brian are hiking towards each other at the opposite ends of a trail that is 21 miles long. Tom hikes uphill at a speed o
Arturiano [62]

Answer:

3.5 hours

Step-by-step explanation:

Distance = 21 miles

Speed * time

Speed * time = distance

Tom speed = 2 mph

Brian = 4 mph

Let time = t

Brian distance + Tom's distance = total distance

4t + 2t = 21

6t = 21

t = 21 / 6

t = 3.5 hours

What is the area of the rectangle?
den301095 [7]

Answer:

50\ units^{2}

Step-by-step explanation:

Plot the figure to better understand the problem

see the attached figure

we know that

If the figure is a rectangle          

then

AB=CD \\AD=BC

The area of the rectangle is equal to

A=B*h

 where  

B is the base  

h is the height  

the base B is equal to the distance AB

the height h is equal to the distance AD  

Step 1

Find the distance AB

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

A(-5,5)\\B(0,-5)

substitute the values

d=\sqrt{(-5-5)^{2}+(0+5)^{2}}\\d=\sqrt{(-10)^{2}+(5)^{2}}\\dAB=\sqrt{125}\ units

Step 2

Find the distance AD

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

A(-5,5)\\D(-1,7)

substitute the values

d=\sqrt{(7-5)^{2}+(-1+5)^{2}}\\d=\sqrt{(2)^{2}+(4)^{2}}\\dAD=\sqrt{20}\ units

Step 3

Find the area of the rectangle

A=AB*AD

we have

dAB=\sqrt{125}\ units\\dAD=\sqrt{20}\ units

substitute

A=\sqrt{125}*\sqrt{20}\\A=\sqrt{2,500}\\A=50\ units^{2}
