Answer:
∡'s are 172.5° and 7.5°
Step-by-step explanation:
x = 23(180-x)
x = 4140 - 23x
add 23x to each side
24x = 4140
x = 4140/24
x = 172.5
Answer:
Translation 2 units to the right and 7 units up
Step-by-step explanation:
Consider the parent function 
and the function 
1. Translate the parent function f(x) two units to the right. The new function will be
2. Translate the function h(x) 7 units up, then the translated function will have the expression

Answer:
(2x + 5)(2x + 1).
(6x - 5)(2x + 1).
Step-by-step explanation:
4x^2 + 12x + 5.
Use the 'ac' method:
a * c = 4 * 5 = 20 so we need 2 numbers whose product is 20 and whose sum is +12.:- 2 and 10 look good, so we write:
4x^2 + 2x + 10x + 5
Now we factor by grouping:-
= 2x(2x + 1) + 5(2x + 1)
= (2x + 5)(2x + 1) (answer).
12x^2 - 4x - 5
ac = 12*-5 = - 60 and we need 2 numbers sum to -4 . these numbers could be -10 and + 6:
12x^2 + 6x - 10x - 5
= 6x(2x + 1) - 5(2x + 1)
= (6x - 5)(2x + 1) (answer).
