Answer:
a = 127°
Step-by-step explanation:
The 3 angles lie on a straight line and have a sum of 180°, that is
15° + a + 38° = 180°
53° + a = 180° ( subtract 53° from both sides )
a = 127°

➷ Just substitute the given value into anywhere you see the term x:
2 x 4^2 + 12
Follow the PEMDAS rule:
(calculate the exponential first)
4^2 = 16
Now we have:
2 x 16 + 12
(now the multiplication needs to be calculated)
16 x 2 = 32
Now we have:
32 + 12
Add them together to get the answer:
44 <== this is the answer

Answer:
<h2>4x⁴yz - 16y³z = 4yz(x² - 2y)(x² + 2y)</h2>
Step-by-step explanation:
Step-by-step explanation:
3/7y + 3/4x = 3/5
y = -3/4x.7/3 +3/5.7/3
y = -7/4x +7/5
so the slope is -7/4
