Answer:
27.5cm^2
Step-by-step explanation:
you can cut the triangle to make two right triangles
so 11 is the height and the width is 2.5 since your cutting the triangle in half
so 11x2.5=27.5 since its a right triangle you have to divide by two 27.5/2=13.75
that's the answer for one of the triangles now multiply it by two since you need the two right triangle to make the other triangle so the answer is 27.5
Answer:
Even function
Step-by-step explanation:
Both powers of x in f(x) = -3x^4 + 7x^2 are even, so f(x) = -3x^4 + 7x^2 is an even function.
Answer:
Step-by-step explanation:
Ir order to find the value of n in the given linear equation: 
you have to perform the properties of equalities to obtain an equivalent equation.
You have to perform these properties in each side of the equation.
Applying the subtraction property (which is the subtraction of the same number to each side of the equation):
Adding 
to each side:
This way you can obtain the value of n
Solving the subtraction of the fractions and simplifying:
Here you go:
ebf = 90-39 = 51
eba = 90
dbe = 90-73 = 17
abf = 90 +51 = 141
abc = 180
