Answer:

Step-by-step explanation:

Recall the area of a triangle formula

$A=\frac{bh}{2}$ where b = base and h = height

The triangle shown has a height of 4cm and a base length 3cm

Using this information we plug in the values into the formula

$A=\frac{4*3}{2} \\4*3=12\\\frac{12}{2} =6$

Hence, the area of the triangle is 6 square centimeters

nirvana33 [79]

Answer:

No, she doesn't have enough varnish for all the floors.

Step-by-step explanation:

Area of the floor, A= 10x6-5x2=50 $m^2$

Since 5 m^2 required 1 liter of varnish.

So, the amount of varnish required for 1 $m^2$ = 1/5= 0.2 liters.

The amount of varnish required for 50 $m^2$ = 0.2X50=10 liters.

Now, as 1 tin has 2.5 liters of varnish.

So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.

Hence, she doesn't have enough varnish for all the floors.

Y=x^2-4x+6 and y=x+2

VashaNatasha [74]

Answer:

(1,3) and (4,6)

Step-by-step explanation:

<u>----Solve by substitution---</u>

$x^2-4x+6=x+2$

Add 4x to both sides

$x^2+6=5x+2$

Subtract 2 from both sides

$x^2+4=5x$

Subtract 5x from both sides

x^2-5x+4 = 0

Factor , = (x-4)(x-1)

First variable : x = 1 and x = 4

-------------------------------

<u>Substitute</u> 1 for x in the 2nd equation

y=(1)+2 = 3

First answer is (1,3)

---------------------------------

<u>Substitute</u> 4 for x in the 1st equation

4^2-4(4)+6 = 6

Second answer: (4,6)
