The the length of a rectangle is 9 centimeters less than four timesfour times its width. its area is 28 square centimeters. find
wel

Let w = width

then

5w-3 = length

w(5w-3) = 14

5w^2-3w = 14

5w^2-3w-14=0

(5w+7)(w-2) = 0

w = {-7/5, 2}

throw out the negative solution leaving

w = 2 centimeters

length:

5w-3 =5(2)-3 =10-3 = 7 centimeters

Determine the discriminant for the quadratic equation -3 = x^2+4x+1 . Based on the discriminant value, how many real number solu
djverab [1.8K]

Answer:

1 real

Step-by-step explanation:

The discriminant is:

b^2-4ac

which comes from the quadratic formula.

The rules are:

If the discriminant is > 0, there are 2 real solutions

If the discriminant is = 0, there is 1 real solution

If the discriminant is < 0, there are 2 imaginary solutions

(there are 2 other situations involving square roots, but these are the most basic ones in Algebra 2 books when you study quadratics)

First, we have to get that quadratic in standard form, which means getting everything on one side of the equals sign and setting it equal to 0:

x^2+4x+4 = 0

where a = 1, b = 4, c = 4

Filling in the discriminant:

4^2-4(1)(4)

gives us

16 - 16 = 0

Therefore, our quadratic has one real solution.  Factor it and see if you'd like, to prove that it is true.

7.4 x 10° + 4.6 x 102
KATRIN_1 [288]

Answer:

4.674 × 10²

Step-by-step explanation:

7.4 x 10° + 4.6 x 10²

Note : 10° = 1 . Any number raise to power zero is 1

7.4 × 1 + 4.6 × 100

7.4 + 460

= 467.4

= 4.674 × 10²
