Step-by-step explanation:
9x² + 6 = 12x
3x² + 2 = 4x
3x² − 4x + 2 = 0
Use quadratic formula.
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-4) ± √((-4)² − 4(3)(2)) ] / 2(3)
x = [ 4 ± √(16 − 24) ] / 6
x = [ 4 ± √(-8) ] / 6
x = (4 ± 2i√2) / 6
x = (2 ± i√2) / 3
Answer:
2.5 m
Step-by-step explanation:
Consider the ramp, the ground and the back of the lorry to form a right triangle where the ramp is the hypotenuse and the distance from the back of the lorry is the adjacent side, x
Using the cosine ratio in the right triangle
cos32° = =
Multiply both sides by 3
3 × cos32° = x, hence
x ≈2.5 m
Answer: 42
Step-by-step explanation: 15 -8=7 90/15=6 6*7=42
Hi,
A hexagon has 720 degrees average!
112 + 133 + 128 + 100 + 120 = 593
720 - 593 = 127
Answer, x = 127 degrees
Answer: She will get a different shade
Step-by-step explanation:
She will not get "Grape Purple" here is why:
The ratio of red to blue cups can be expressed as a fraction of:
2/3
If we express Miya's mix as a fraction we get:
8:14
If we simplify that it becomes:
4/7
4/7 is not equal to 2/3.
