Answer:
55?
Step-by-step explanation:
110 would be the last year for two and then divide by two
<h2>
Answer:</h2>
9 inches
<h2>
Step-by-step explanation:</h2>
Let x be the length of the side of the square.
If the base of the triangle is 3 times as long as the side of the square, it is 3 times x, or 3x.
The same can be said for the legs, which is 1 inch more than twice the side of the square, so 2x + 1.
The triangle can therefore be thought to look like the triangle below.
The perimeter is therefore (2x+1) + (2x+1) + 3x, which is 7x + 2.
The sum of perimeters of both the square and triangle is 46.
The perimeter of the square is 4x, so the sum of perimeters is 4x + (7x+2), or 11x + 2.
11x + 2 = 46, so 11x = 44.
x is therefore 4
The leg is 2x + 1, so the leg is 8 + 1, so the length of the leg is 9 inches.
Answer:
1. x = 15
2. x = - 9/7
3. x = 11/3
Step-by-step explanation:
<u>Part</u><u> </u><u>one</u><u>,</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>3</u><u>+</u><u>1</u><u>/</u><u>5</u><u>x</u>
to find x-intercept/zero, substitute y= 0
0 = 3 + 1/5
multiple both sides of the equation by five.
0 = 15 + x
move the variable to the left.
-x=15
change the signs on both of the equations.
x = -15
your solution is x = -15.
<u>Part</u><u> </u><u>two</u><u>,</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>-7x</u><u> </u><u>-9</u>
Move variable to the left hand side and change its sign.
7x = -9
Divide both sides of the equation by 7.
x=-9/7
Solution is x = - 9/7
<u>Part</u><u> </u><u>three</u><u>,</u><u> </u><u>y</u><u>=</u><u> </u><u>1</u><u>1</u><u> </u><u>-3x</u>
to find x intercept y and substitute for zero.
0= 11 - 3x
move variable to the left hand side and change its sign.
3x= 11
divide both sides by 3.
x= 11/3
Solution is x = 11/3
A right triangle has legnths that have a special relationship to each other
if you have legs legnth a and b and hypotonuse legnth c
a^2+b^2=c^2 yeilds a true statement
so the hypotonuse is normally the longest side so 41 cm is the hypotonuse
c=41
a=7
b=40
subsitute
7^2+40^2=41^2
49+1600=1681
1649=1681
false
this is not a right triangle
