2L + 2W = 88<br> L = W + 12<br> What are the dimensions?
liraira [26]

Answer:the length of the rectangle is 28

The width of the rectangle is 16

Step-by-step explanation:

The given equations are set up to determine the dimensions of a rectangle. L represents the length of the rectangle. W represents the width of the rectangle. Let us label

2L + 2W = 88 as equation 1.

We would substitute L = W + 12 into equation 1, it becomes

2(W + 12) + 2W = 88

2W + 24 + 2W = 88

4W + 24 = 88

4W = 88 - 24 = 64

W = 64/4 = 16

Substituting W = 16 into L = W + 12, it becomes

L = 16 + 12 = 28

Does someone know this answer I will give you a brainiest
Phoenix [80]

Answer:

10^17

Step-by-step explanation:

When doing this you use the Product Rule of Exponents where you add the exponents when the base number is the same. So in this case, 8+9=17. So the final result would be 10^17.

(PLEASE HELP )Use the discriminant to find the number of real solutions of the equation 3x^2-5x+4=0. show your work.
Softa [21]

Answer:

0 real solutions

Step-by-step explanation:

The discriminant (D) is given by the formula:

D=b^2-4ac

Where a,b, and c are gotten from the standard form of a quadratic equation, which is  ax^2+bx+c=0

The equation given is  3x^2-5x+4=0

<em>From this we can say that a = 3, b = -5, & c = 4. Plugging these into the discriminant formula we get:</em>

D=b^2-4ac\\D=(-5)^2-4(3)(4)\\D=-23

<u>There are 3 things that we can find from the value of discriminant:</u>

1. If D=0, there are 2 equal, real roots

2. if D>0, there are 2 distinct real roots

3. if D<0, there are no real roots, rather 2 imaginary roots

Since the value of the discriminant is negative (D<0), we can say that there are no real solutions for the equation given.
