The product of two rational numbers is always rational.
Answer:
x=2.6
Step-by-step explanation:
We can use the Pythagorean theorem to find the third side
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
3^2 + x^2 = 4^2 where x is the unknown side
9 + x^2 = 16
Subtract 9 from each side
x^2 = 16-9
x^2 = 7
Take the square root of each side
sqrt(x^2) = sqrt(7)
x =2.645751311
Rounding to the nearest tenth
x = 2.6
Because they don't have the same answer
A triangle is a polygon with three edges and three vertices, perimeter of ΔABC = 36cm.
<h3>Congruent triangles are what?</h3>
Congruent triangles are two triangles that are identical in terms of their size and shape. One of two congruent triangles remains congruent even if it is rotated, flipped, or turned. Two triangles must have the same sides in order for them to have the same angles and, as a result, to be congruent.
Triangles with equal measures are congruent.
36cm = perimeter of ΔABC
Here we have,
ΔABC ≅ Δ XYZ
So,
Therefore, perimeter of ΔABC = 36cm

Answer:
Dollars
Quantitative
Step-by-step explanation:
The units of measurement of variable of interest are Dollars because the calculated mean and standard deviation of the data set of variable of interest indicates the measurements constitutes of dollars. The type of data is quantitative because the data can be meaningfully represented as numerically.
