Answer:

4 cars

Step-by-step explanation:

18 people(friends)

5x4=20

Which means there is going to be 2 extra seats. Four cars with five seats 3x5=15. This means you would need 3 more seats so you need a whole other car. Which means you have 4 cars.

Hope this helps.

Step-by-step explanation:

Area of rectangle = 408 in²

Length = 3x-2 and width = x

The area of a rectangle is given by :

A = lb

(3x-2)x = 408

x = 12 inch and x = -11.33 in

Neglecting negative value,

The width of rectangle = 12 inch

The length of rectangle = 3x-2 = 3(12)-2 = 34 inch

12.

Base of triangle = 2x+2

Height = x

The area of a triangle is given by :

A=\dfrac{1}{2}bh\\\\600=\dfrac{1}{2}\times (2x+2)x\\\\600=(x+1)x

x = 24 cm and x = -25 cm

Neglecting negative value, x = 24 cm

Base = 2x+2 = 2(24)+2 = 50 cm

Hence, this is the required solution.

How do you solve this??? Someone help. We just started learning Pythagoras Theorems..
ira [324]

Answer:

It means length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

Step-by-step explanation:

to solve this...we think that distance from ben to church is x...now a triangle is formed.

length of the hypotenuse is 13cm

{13}^{2}  =  {8}^{2}  +  {x}^{2}

169  = 64 +  {x}^{2}

169 - 64 =  {x}^{2}

105 =  {x}^{2}

\sqrt{105}  = x

x = 10.246950766
