Base = x
height = x-4
Area = .5 * height * base
48 = .5 * (x-4) * x
96 = x^2 -4x
x^2 -4x -96=0
x = 12
base = 12
height = 8

Find the Area Of each circle.
Levart [38]

The area of the circle A and B is 86.54 inches and 124.62 mm

According to the statement

we have given that the radius of the circle A and b and we have to find the area of the given circle.

So, we know that the

The area enclosed by a circle of radius r is πr².

So, For area of the circle

For condition A :

diameter = 10.5 inches

then radius = 5.25

Area = πr²

Area = 3.14*27.56

Area = 86.54 inches

Now, For condition B :

radius = 6.3 mm

Area = πr²

Area = 3.14*39.69

Area = 124.62mm

So, The area of the circle A and B is 86.54 inches and 124.62 mm

Solve for the value of X.
Mkey [24]
The answer is 40°
i will tell you how,
Total angle sum of any triangle is 180°
∠A + ∠B  + ∠E = 180°
70° + 80° + ∠E = 180°
solve for ∠E
∠E = 30°
Now solve use ∠BDE,
∠B + ∠D + ∠E = 180°
20° + 90° + 30° + x = 180°           (in triangle DEB, ∠E = 30 + x ) (∠D is 90°)
solve for x
there fore, x = 40°

24. Use the intercepts to graph the equation.
romanna [79]

Answer:

See below ~

Step-by-step explanation:

<u>Finding x-intercept</u>

  • Take y = 0
  • 2x - 5(0) = 10
  • 2x = 10
  • x = 5
  • x-intercept is at (5, 0)

<u>Finding y-intercept</u>

  • Take x = 0
  • 2(0) - 5y = 10
  • -5y = 10
  • y = -2
  • y-intercept is at (0, -2)

<u>Graph (with points marked)</u>

Calculate the factorization 16w^2+48w+36=(4w+[1])^2
stiv31 [10]

Answer:

  [1] = 6

  x = -3/2 is the root

Step-by-step explanation:

A perfect square trinomial is of the form ...

  (a + b)² = a² +2ab +b²

You have ...

  • a²=16w²   ⇒   a = 4w
  • b² = 36   ⇒   b = 6
  • 2ab = 2(4w)(6) = 48w

Then the factorization is ...

  16w² +48w +36 = (4w +6)²

This will be zero when x = -6/4 = -3/2.
