\/(5x) = x\/5
[\/(5x]² = [x\/5]²
5x = 5x²
5x²-5x = 0
5x(x-1) = 0
5x = 0 --> x = 0
x-1 = 0 --> x = 1

The written portion of bens driving test had 40 questions Ben correctly answered 12 more questions than he missed how many quest

lilavasa [31]

We wil name x to the amount of correctly answered questions. Then, we get:

$(x-12)+x=40$ $2x-12=40$ $2x=40+12$ $2x=52$ $x=\frac{52}{2}$ $x=26$

Ben had 26 correct answers, so he missed 40-26= 14.

Pls help me i need to fill in the boxes that dont have anything in them but i aldo need to fill in the one that says "A="

Step-by-step explanation:

$\bf \red { Area: \; \boxed{ 24 } units^2}$

Formula of area of a parallelogram is :

Area of parallelogram = b × h

○ b denotes base

○ h denotes height

Here,

Base of the parallelogram is 6 units and height is 4 units.

→ Area of the parallelogram = 6 units × 4 units

→ Area of the parallelogram = 24 units²

$\therefore$ Area of the parallelogram is 24 units².

$\bf \purple { Perimeter: \; \boxed{ 22 } units}$

Perimeter of parallelogram = Sum of all sides

Since, opposite sides of a parallelogram are equal. So,

○ First side = 6 units

○ Second side = 5 units

○ Third side = 6 units

○ Fourth side = 5 units

→ Perimeter = ( 6 + 5 + 6 + 5 ) units

→ Perimeter = ( 12 + 10 ) units

→ Perimeter = 22 units

$\therefore$ Perimeter of the parallelogram is 22 units.

$\boxed{ \sf { AREA \; FORMULA }}$

$\boxed { \sf { A = Base \times Height }}$
