What is 37+8x=4(7-x)

Mathematics
1 answer:
nadezda [96]3 years ago
7 0
Simplifying
37 + 8x = 4(7 + -1x)
37 + 8x = (7 * 4 + -1x * 4)
37 + 8x = (28 + -4x)

Solving
37 + 8x = 28 + -4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4x' to each side of the equation.
37 + 8x + 4x = 28 + -4x + 4x

Combine like terms: 8x + 4x = 12x
37 + 12x = 28 + -4x + 4x

Combine like terms: -4x + 4x = 0
37 + 12x = 28 + 0
37 + 12x = 28

Add '-37' to each side of the equation.
37 + -37 + 12x = 28 + -37

Combine like terms: 37 + -37 = 0
0 + 12x = 28 + -37
12x = 28 + -37

Combine like terms: 28 + -37 = -9
12x = -9

Divide each side by '12'.
x = -0.75

Simplifying
x = -0.75

Solve 3x2+7x+1=0 using the quadratic formula.
NNADVOKAT [17]

Answer:

x=\frac{-7+-\sqrt{37} }{6}

Step-by-step explanation:

This (±) goes between the -7 and \sqrt{37}

3x^{2} +7x+1=0

ax^{2} +bx+c

-b ± \sqrt{b^2-4ac}/2a

-7 ± \sqrt{(7)^2-4(3)(1)}/2(3)

-7 ± \sqrt{49-12}/6

-7 ± \sqrt{37}/6

On a piece of paper, use a protractor to construct right triangle DEF with DE=4 in. , m∠D=90° , and m∠E=45° .
uysha [10]

Answer: DF = 4 in

Step-by-step explanation:

Here in triangle DEF,

In which DE = 4, m\angle D=90^{\circ} , and m\angle E=45^\circ}

Since, tan E = \frac{FD}{DE}

⇒ tan 45^{\circ} = \frac{FD}{DE}

⇒  1 = \frac{FD}{4}

⇒  FD = 4

Thus, first option is correct.
