Answer:
1. x = 3 or x = -8
2. x = -2 or x = 10
Step-by-step explanation:
<u>1. |2x + 5| = 11</u>
2x + 5 = 11 Or 2x + 5 = -11
-5 -5 -5 -5
----------------- -----------------
2x = 6 2x = -16
/2 /2 /2 /2
----------------- -----------------
x = 3 x = -8
<u>2. 3|x - 4| + 1 = 19</u>
3|x - 4| + 1 = 19
-1 -1
----------------------
3|x - 4| = 18
/3 /3
----------------------
|x - 4| = 6
x - 4 = -6 Or x - 4 = 6
+4 +4 +4 +4
----------------- -----------------
x = -2 x = 10
Answer:
<h2>x = 29°</h2>
Step-by-step explanation:
From the question the angles lie on a straight line which means that the sum of their angles add up to 180°
Since angles on a straight line add up to 180°
To find the value of x add up all the angles and equate it to 180 to find x
That's
x + 4 + 147 = 180
x + 151 = 180
x = 180 - 151
We have the final answer as
<h3>x = 29°</h3>

When you multiply the equation out and you simplify like terms you get.
2x^2 + 6xy + 4y^2
Answer:
300 km
Step-by-step explanation:
3 hours and 45 minutes = 3
Speed = 80 km per hour.
80 × 3 = 240 km
80 × = 60
240 + 60 = 300
