Which two numbers multiply to 60 and add to -2?
USPshnik [31]
xy=60\\
x+y=-2\\\\
xy=60\\
x=-y-2\\\\
(-y-2)y=60\\
-y^2-2y-60=0\\
y^2+2y+60=0\\
y^2+2y+1+59=0\\
(y+1)^2=-59


There are no such numbers in real numbers.

A triangle has side lengths of (1.3f+2.9g)(1.3f+2.9g) centimeters, (1.1f-7.7h)(1.1f−7.7h) centimeters, and (2.3h+1.5g)(2.3h+1.5g
VikaD [51]

Answer:

Perimeter of the triangle = (2.4f+4.4g-5.4h) centimeters.

Step-by-step explanation:

It is given that, a triangle has side lengths of (1.3f+2.9g) cm, (1.1f-7.7h)cm, and (2.3h+1.5g) cm.

We have to find the expression which represents the perimeter, in centimeters, of the triangle.

Perimeter of a triangle = Sum of its all the sides.

Perimeter=(1.3f+2.9g)+(1.1f-7.7h)+(2.3h+1.5g)

On combining like terms, we get

Perimeter=(1.3f+1.1f)+(2.9g+1.5g)+(-7.7h+2.3h)

Perimeter=2.4f+4.4g+(-5.4h)

Perimeter=2.4f+4.4g-5.4h

Therefore, the perimeter of the triangle is (2.4f+4.4g-5.4h) centimeters.

The area of a triangle is the product of the base of the triangle times the height of the triangle, divided by two.
trasher [3.6K]

Answer:

Step-by-step explanation:

Almost correct.  I'd write this statement as follows:

"The area of a triangle is the product of the base and height of the triangle, divided by two."

or...

"The area of a triangle is half the product of the base and height."
