Answer:
100°
Step-by-step explanation:
The angle between chords is the average of the intersected arc angles.
∠FKJ = ½ (84° + 76°)
∠FKJ = 80°
∠HKJ is supplementary to ∠FKJ.
∠HKJ = 180° − 80°
∠HKJ = 100°
Answer:
It should be -36 because there are no parentheses if it was (-6)² then it would be 36 but since there are no parentheses its like -(6²) which is -36
The expression is simplified to give -7x^2 - 11x
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions that contains variables, constants, factors and coefficients.
They are also made up of arithmetic operations such as addition, subtraction, multiplication, division, etc.
From the information given, we have;
(- x^2 - 5x ) - ( 6x^2 + 5x)
expand the bracket
-x^2 - 5x - 6x^2 - 5x
collect like terms
-7x^2 - 11x
Thus, the expression is simplified to give -7x^2 - 11x
