(7, 5)
because u round (6.5, 4.5) to the nearest tenth
Step-by-step explanation:
So 4x2+9 has no linear factors with Real coefficients. It is possible to factor it with Complex coefficients.
Answer:
x = 21
Step-by-step explanation:
The 2 angles form a straight angle and are supplementary, thus
7x + 9 + 2x - 18 = 180, that is
9x - 9 = 180 ( add 9 to both sides )
9x = 189 ( divide both sides by 9 )
x = 21
1
Add 1111 to both sides
5x\ge 31+115x≥31+11
2
Simplify 31+1131+11 to 4242
5x\ge 425x≥42
3
Divide both sides by 55
x\ge \frac{42}{5}x≥542
6+1/343+36+1/81−27−36+1/81-27-243+1/256+1/144+1/8+1/5
