The "compound amount" formula is A = P(1+r)^t.

Here, the Amount  A(x) is (x)(1+0.03)^1= 1.03x.

Please be clearer about what you are asking here.  I assume you just wanted to be told that you are right.

the length of a rectangle exceeds its width by 17 inches, and the area is 18 square inches. what are the length and width of the
dimaraw [331]

The length and width of the rectangle are 18 in and 1 in, respectively.

<h3>Quadrilaterals</h3>

There are different types of quadrilaterals, for example, square, rectangle, rhombus, trapezoid, and parallelogram.  Each type is defined accordingly to its length of sides and angles. For example, in a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

The area of a rectangle can be found for the formula : b*h, where b = base and h =height.

For this question, the length exceeds its width by 17 inches - L=W+17. Here, the length is the base and the width is the height. Thus,  from the value of area given, you can find the values of the length and width of the rectangle.

A=b*h

18=(W+17)*W

18=W²+17W

W²+17W-18=0

Solving this quadratic equation, you have:

w_{1,\:2}=\frac{-17\pm \sqrt{17^2-4\cdot \:1\cdot \left(-18\right)}}{2\cdot \:1}

w_{1,\:2}=\frac{-17\pm \:19}{2\cdot \:1}

w1=1 and w2= -18

For dimensions, only positive numbers must be used. Then, the width is equal to 1 inch.

As, the area (l*w) is 18 in², see.

18=l*w

18=l*1

l=18 in

What's the distributive property when solving the equation 7(x+5)-x=42
Marysya12 [62]
When you are doing distributive property, it can only happen if a number or exponent is before the bracket. From this equation, you can solve for x like so:

7(x+5)-x=42

7x+35-x=42 -Using distributive property (Multiplication)

6x=7 -Collecting like terms.

x= 7/6 -The answer.

Therefore x would equate to 7/6.
