the imaginery hight line you draw in the middle of the triangle should split the 6cm base in half to 3cm and the outside of the tryangle is 6cm.
pythagorian theorem formula states:
c^2 =a^2 +b^2
c=6cm
b = 3cm
a=?
6^2 =3^2+a^2
36=9+a^2
36-9=a^2
a^2 =27

Ye i solved this a different way
so in order to see how many 20km of gas is needed, we first need to see how many miles thats worth.
1 mile = 1.6km
1.6 goes into 20, 12.5 times
12. 5 is our magic number. Now we take 12.5 and divide it by 40 and not the other way around.
now we're left with 0.3
voila it"s done, hope this simplifies this s bit, have a nice day
Step-by-step explanation:
if 1 gallon gets you 40 miles, then x gallons will get you 12.5 miles., Solve for x, x=12.5/40=0.3125.

Answer: 95cm^2
Step-by-step explanation:
Make smaller shapes then add all the areas up together at the end.
6*4 = 24cm^2
3*2 = 6cm^2
For the base of the triangle:
10+3 = 13cm^2
Area of a triangle = (b*h)/2
(13*10)/2 = 65cm^2
65cm^2 + 13cm^2 + 24cm^2 = 95cm^2

The equation that represents Jacob's age is x = y + z + 2
From the question, the following information was provided :
Jacob's age is two years more than the sum of the ages of his siblings Becky and Micah.
This above information can be represented with the equation below
Jacob = 2 + ( Becky + Micah) (equation 1)
If :
x represents Jacob's age
y represents Micah's age
z represents Becky's age
Equation 1, can be rewritten as x = y + z + 2
Micah's age can be determined by making Micah the subject of the formula in the above equation
Micah = Jacob - Becky - 2 (equation 2)
If :
x represents Micah's age
y represents Becky's age
z represents Jacob's age
Micah's age can be rewritten as :
x = z - y - 2
Becky's age age can be determined by making Becky the subject of the formula in the first equation.
Becky = Jacob - Micah - 2 (equation 3)
If:
x represents Becky's age
y represents Jacob's age
z represents Micah's age
Equation 3 can be rewritten as :
x = y - z - 2

y = a (x - h)² + k
We manipulate the given equation to be the same as the vertex form. First we transpose the constants to the left-hand side.
y - 14 = 5x² + 20x
Then, we factor out in right hand side the coefficient of the x² term.
y- 14 = 5 (x² + 4x)
We divide the coefficient of the x term with 2 and take its square. We add this value to both sides of the equation but we should remember that in the left-hand side we should multiply this value with five to keep it balanced.
y - 14 + 20 = 5 (x² + 4x +4)
We simplify the right-hand side as:
y + 6 = 5 (x + 2)²
We can now manipulate further the equation above in the vertex form. Thus,
y= 5 [ x- (-2)]² - 6
Answer:
y = 5(x+2)^2 - 6
