If the length of a rectangle is x + 4 and the width is 2x – 3, what is the area?

1 answer:

The area of a rectangle is the length times the width.

$(x+4) \times (2x-3)=2x^2-3x+8x-12=2x^2+5x-12$

$a_1=4\\
a_2=2*a_1=8\\
a_3=2*a_2=2^2*a_1=4*4=16\\
a_4=2^3*a_1=8*4=32\\
a_5=2^4*a_1=16*4=64\\

4+8+16+32+64=124

4(2x - 5) + 15 = 11 Write the steps you will use to solve the equation and explain each step.

vagabundo [1.1K]

First, multiply 4*2x-4*-5= 8x-20.
Second, add 15 to 8x-20
Third, that would equal 8x-20+15=11
Fourth, 15+-20= -5
Fifth, 8x-5=11
Sixth, add +5 to -5 and +5 to 11= 8x=16
Last, do 8x/8x and 16/8x
The answer is x=2

Find the value of x. Please help. I am confused

Oxana [17]

Answer:

x=30

Step-by-step explanation:

Exterior Angle Theorem = the exterior angle of a triangle is equal to the sum of the two opposite interior angle

Thus, 2x+6+36=4x-18

2x+42=4x-18 add 18 to both side

2x+60=4x minus 2x

60=2x

x=30
