Answer:
y = 20 x = 6
Step-by-step explanation:
1 (3x+ 2y = 58 ------------> -3x + -2y = -58
1x + 2y = 46 --------------> 1x + 2y = 46
____________
-2x = -12
-----------------
-2x -2x
x = 6
3(6) + 2y = 58
18 + 2y = 58
-18 -18
------------------
2y = 40
----- -----
2y 2y
y = 20

Answer:
- f(x²) = x² +5
- (f(x))² = x² +10x +25
Step-by-step explanation:
Put the argument in place of x and evaluate the desired expression.
__
1. f(x²) = x² + 5 . . . . . . straight substitution for x
__
2. (f(x))² = (x +5)²
= (x +5)(x +5) = x(x +5) +5(x +5) = x² +5x +5x +25
(f(x))² = x² +10x +25

Answer:
176°
Step-by-step explanation:
The total of exterior angles is 360°, so one of those for the regular polygon will be 360°/90 = 4°. The adjacent interior angle is the supplement of this.
The interior angles measure 180° -4° = 176°.
