I think 121
406 + 94 = 500 and 180 + 199 = 379.
Subtract that and 121 is what’s left.
<h3>Area of shape P = 12 square cm</h3>
Explanation:
Shape P is a triangle with the base of 4 units across the horizontal portion up top.
The height of the triangle is 6 units. Count the spaces down the middle of the triangle and you should get 6 spaces.
Area = base*height/2
Area = 4*6/2
Area = 24/2
Area = 12 square cm.
Answer:
x = 18 (Smaller number)
y = 35 (Larger number)
Step-by-step explanation:
To solve, begin by setting up a system of equations.
'x' being the smaller number, while
'y' is the larger number.
We can construct the equations:
x + y = 53
3x = y + 19
Rearrange the second equation to equal 'y':
3x - 19 = y
Plug this value of 'y' into the first equation:
x + 3x - 19 = 53
Combine like terms and simplify:
4x - 19 = 53
4x = 72
x = 18
Plug in this value for 'x' into an equation to solve for 'y':
18 + y = 53
y = 35.
Answer:
Step-by-step explanation:
We see that this is a rectangle triangle, and that the ZY side is the hypotenuse.
It's length is then square root of the sum of the squares of the other sides:
So, in this case:
The 8 and 3 numbers are easy to get from the graphic... and the order doesn't matter (8² + 3² = 3² + 8²).
That's an easy rule to remember.
I hope it helps.
