Mathematics

kumpel [21]3 years ago
5 0

Answer:

It is B

Step-by-step explanation:

To solve this, you must use factoring:

You must find two numbers that multiply to -6, and add up to 5(y).

y^{2} +5y-6=0 turns into...

(y+6)(y-1)=0 because 6 × -1 = -6, and 6-1 = 5

after that, find the roots by solving for the x in each of the parentheses

so, x=-6 and x=1

Answer:

The largest side of given triangle is: AB

Step-by-step explanation:

In order to find the largest side, we have to find all the triangles first.

The two angles at point A will sum up to 180° as the angles on the straight line are supplementary.

So,

136 + Angle\ A = 180\\Angle\ A = 180-136 = 44

∠A = 44°

∠C = 71°

The sum of interior angles of a triangle is 180°

Using this:

∠A+∠B+∠C = 180°

44°+∠B+71° = 180°

∠B+115° = 180°

∠B = 180°-115°

∠B = 65°

In a triangle, the side opposite to the largest angle is the largest. In the given triangle, ∠C is the largest so the side AB which is opposite to ∠C is the largest.

Hence,

The largest side of given triangle is: AB

If f(x)= x2 + 2x - 6 and g(x)= 3x2 - 5x - 7, find f(x)-g(x).
dezoksy [38]

Answer:

- 2x² + 7x + 1

Step-by-step explanation:

f(x) - g(x)

= x² + 2x - 6 - (3x² - 5x - 7) ← distribute parenthesis by - 1

= x² + 2x - 6 - 3x² + 5x + 7 ← collect like terms

= - 2x² + 7x + 1

Answer:

here it is in order

x^2 = 1 / x ^ -2

x^4 ÷ x^3 = x

(x^2)^2 = x^4

x^3 × x^3 × x^3 = x ^ 9
