How can i solve by completing the square 4r^2-28r=-49
Natalija [7]
To complete the square, the second degree term must have a coefficient of 1.
Since the second degree term here has a coefficient of 4, we start by dividing each term on both sides by 4.

4r^2 - 28r = -49

\dfrac{4r^2}{4} - \dfrac{28}{4}r = -\dfrac{49}{4}

r^2 - 7r = -\dfrac{49}{4}

Now we can complete the square.
First, we need to find what number completes the square.
We take the coefficient of the first degree term, -7 in this case.
Divide it by 2 and square it. -7 divided by 2 is the fraction -7/2.
Now we square -7/2 to get 49/4.
We add 49/4 to both sides.

r^2 - 7r + \dfrac{49}{4} = -\dfrac{49}{4} + \dfrac{49}{4}

(r - \dfrac{7}{2})^2 = 0

r - \dfrac{7}{2} = 0

r = \dfrac{7}{2}

Jennie purchased a box of crackers from the deli. The box is in the shape of a triangular prism. If the volume of the box is 3,2
Mnenie [13.5K]

Answer:

Height of the triangular face of the box is 12 cm.

Step-by-step explanation:

This question is not complete; please find the question as the attachment.

Volume of a triangular prism = Area of the triangular base × height

It's given in the question, Volume of the prism = 3240 cm³

Height of the prism = 30 cm

By substituting these values in the formula,

3240 = B × 30

B = \frac{3240}{30}

B = 108 cm²

Area of the triangular face (B) = \frac{1}{2}(\text{Base})\times (\text{Height of the triangular base})

108 = \frac{1}{2}\times (18)\times h

108 = 9h

h = 12 cm

Therefore, height of the triangular face of the prism is 12 cm.

The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 and 5.6 feet. What is the height of the trapezoid
olasank [31]

Answer:

The height is 8.3 feet

Step-by-step explanation:

The area of a trapezoid is calculated using the formula:

Area=½(sum of bases)*height

We substitute area=70.55, and the base lengths 11.4 and 5.6 feet and solve for the height.

70.55 =  \frac{1}{2} (11.4 + 5.6)h

70.55 =  \frac{1}{2} (17)h

70 .55 = 8.5h

h =  \frac{70.55}{8.5}

h = 8.3
