How many is 7= 12 + 5h With procedure

1 answer:

8 0

H= -1 here's why:

7 = 12 + 5h

First you subtract 12 from both sides then the equation would look like:

-5 = 5h

Then you would divide the equation by 5 from both sides it would then look like:

-1 = h

Answer:

a) C x +x +x +3x +3x = 18

b) x = 2

c) 2 cm, 6 cm

Step-by-step explanation:

a) The sum of the lengths of the sides is equal to the length of the perimeter. The appropriate equation is ...

x +x +x +3x +3x = 18

b) Simplifying, the equation becomes ...

9x = 18

x = 2 . . . . . divide by 9

c) The shorter sides are x = 2 cm.

The longer sides are 3x = 6 cm.

Suppose a and b are the solutions to the quadratic equation 2x^2-3x-6=0. Find the value of (a+2)(b+2).

KonstantinChe [14]

Answer:

(a+2)(b+2) = 4

Step-by-step explanation:

We are given the following quadratic equation:

$2x^2-3x-6=0$

Let a a and b be the solution of the given quadratic equation.

Solving the equation:

$2x^2-3x-6=0\\\text{Using the quadratic formula}\\\\x = \dfrac{-b \pm \sqrt{b^2-4ac}}{2a}\\\\\text{Comparing the equation to }ax^2 + bx + c = 0\\\text{We have}\\a = 2\\b = -3\\c = -6\\x = \dfrac{3\pm \sqrt{9-4(2)(-6)}}{4} = \dfrac{3\pm \sqrt{57}}{4}\\\\a = \dfrac{3+\sqrt{57}}{4}, b = \dfrac{3-\sqrt{57}}{4}$

We have to find the value of (a+2)(b+2).

Putting the values:

$(a+2)(b+2)\\\\=\bigg(\dfrac{3+\sqrt{57}}{4}+2\bigg)\bigg(\dfrac{3-\sqrt{57}}{4}+2\bigg)\\\\=\bigg(\dfrac{11+\sqrt{57}}{4}\bigg)\bigg(\dfrac{11-\sqrt{57}}{4}\bigg)\\\\=\dfrac{121-57}{156} = \dfrac{64}{16} = 4$
