Answer:
What figure
Step-by-step explanation:
126 2/5 i multiplied them separately and added the two products together
Answer: (-6,-5)
Step-by-step explanation:
2x - 2y = -2 ............ equation 1
3x - y = -13 ................ equation 2
solving by substitution method
from equation 2 , make y the subject of the formula, we have
y = 3x + 13 .............. equation 3
substitute equation 3 into equation 1 , we have
2x - 2 (3x + 13 ) = -2
2x - 6x - 26 = -2
-4x - 26 = -2
-4x = -2 +26
-4x = 24
x = 24/-4
x = -6
substitute x = -6 into equation 3 to get the value of y , we have
y = 3(-6) + 13
y = -18 +13
y = -5
The height of the triangle is 19.596 centimeter, if a right isosceles triangle has an area of 192 square centimeters.
Step-by-step explanation:
The given is,
Area of right isosceles triangle is 192 square centimeters
Step:1
Formula for area of right isosceles triangle is,
............................(1)
Where, a - Sides of triangle
a = h = b
Here, h - Height of triangle
b - Base of triangle
From given,
Area, A = 192 square centimeters
Equation (1) becomes.


= 384

Take square root on both sides,

a = 19.596 centimeters
Height of right isosceles of triangle, a = h = 19.596 centimeters
Result:
The height of the triangle is 19.596 centimeter, if a right isosceles triangle has an area of 192 square centimeters.
Answer:
The area of the pentagon is 193.45 square inches.
Step-by-step explanation:
In order to solve this question we need to use the appropriate formula for the pentagon's area shown below:
area = (p*a)/2
Where p is the perimeter for the pentagon and a is it's apothem.
area = (53*7.3)/2 square inches
area = 386.9/2 square inches
area = 193.45 square inches
The area of the pentagon is 193.45 square inches.
