Describe in your own words how to factor of negative one out of an addition or subtraction expression

1 answer:

fomenos2 years ago

Answer:

Expressions with fractional or negative exponents can be factored by pulling out a GCF. Look for the variable or exponent that is common to each term of the expression and pull out that variable or exponent raised to the lowest power. These expressions follow the same factoring rules as those with integer exponents.

In the diagram below, O is circumscribed about quadrilateral DEFG. What is the value of x?

Fofino [41]

Answer:

A. 70

Step-by-step explanation:

The given quadrilateral DEFG is a cyclic quadrilateral.

$\angle F+70\degree=180\degree$ ...opposite angles of a cyclic quadrilateral are supplementary.

$\implies \angle F=180\degree-70\degree$

$\implies \angle F=110\degree$

The sum of angles in a quadrilateral is 360 degrees.

$x-10+70+110+120=360$

$x+290=360$

$x=360-290$

$x=70\degree$

If I have a triangle with a leg of 4 and a leg of 3 what is the length of the hypotenuse

Dmitrij [34]

Answer:

5

Step-by-step explanation:

To solve for hypotenuse we use the Pythagorean theorem:

$a^2+b^2=c^2$

In this theorem:

c= hypotenuse

a = leg

b = leg

Substitute into theorem:

$4^2+3^2=c^2$

$16+9=c^2$

$25=c^2$

(square root both sides)

$5=c$

Therefore the hypotenuse has a length of 5.

Please say thanks if correct :)

Write the quadratic equation in standard form:<br> 7x + 8 + 2x2<br> 2x + 1 + x2

JulsSmile [24]

Answer:

$3x^2 + 9x +9$

Step-by-step explanation:

Given

$(7x + 8 + 2x^2) + (2x + 1 + x^2)$

Required

The result in standard form

We have:

$(7x + 8 + 2x^2) + (2x + 1 + x^2)$

Remove brackets

$7x + 8 + 2x^2 + 2x + 1 + x^2$

Collect like terms

$7x+ 2x + 8 + 1 + 2x^2+ x^2$

$9x + 9+ 3x^2$

The standard form of a quadratic equation is:

$ax^2 + bx + c$

So, we have:

$9x + 9+ 3x^2$

$3x^2 + 9x +9$

I need help with this question I will give brainliest

guajiro [1.7K]

Answer:

No

Step-by-step explanation:

In order for there to be a right triangle formed, this must satisfy pythagoran's theorm thingy:

a^2+b^2=c^2

7^2+15^2=274

22^2= 484

since 274 isnt equal to 484

There is not a right triangle formed here
