Answer:
20%
Step-by-step explanation:
10-8=2
If 10 is equal to 100%
So, 2 is 20%
Answer:
5 rows of 4 each
4 rows of 5 each
2 rows of 10 each
10 rows of 2 each
1 row of 20
20 rows of 1
Step-by-step explanation:
Answer:
(x, y) = (22, 35)
base angle theorem; angle sum theorem
Step-by-step explanation:
Base angles theorem:
Angles opposite congruent sides are congruent:
3x -11 = 2x +11
x = 22
__
Angle sum theorem:
The sum of angles in a triangle is 180°.
(3x -11)° +(2x +11)° +2y° = 180°
5x° +2y° = 180°
2y = 180 -5(22) . . . . . divide by °, subtract 5x, substitute for x
y = 35 . . . . . . . . . divide by 2
Answer:
a^3 + b^3 + ab^2 + a^2b
Step-by-step explanation:
Here, we want to find a product
we proceed as follows;
(a + b)(a^2 + b^2)
= a(a^2 + b^2) + b(a^2 + b^2)
= a^3 + ab^2 + a^2b + b^3
= a^3 + b^3 + ab^2 + a^2b
Since the matrices have different dimensions, it is not possible to calculate the expression...
