You have to subtract 3.2 from 3.5 to get x. 0.3+ 3.2=2.5 so x=0.3
Answer: i dont understand
Step-by-step explanation:
#1. B
<span>(z * z^2 + z * 2z + z * 4) – (-2 *z^2 – (-2) 2z – (-2) 4)
Z^3 + 2z^2 + 4z – 2z^2 -4z – 8
Z^3 + 2z^2 – 2z^2 + 4z – 4z – 8
Z^3 - 8
</span>
#2 and #3. D
<span>(x + y)(x + 2)
x^2 + 2x + yx + 2y
</span>
#4. D.
<span>(x - 7)(x + 7)(x- 2)
x^2 + 7x – 7x -49
x^2 + x – 49
x^2 -49
(x^2 – 49 ) (x – 2)
x^3 – 2x^2 – 49x + 98
</span>
#5. C
(y - 4) = 0
y = 4
(x + 3)= 0
x = -3
#6. A and B
Though there are many common factors of 24, 36, and 60, thegreatest common factor (GCF) of 24, 36, and 60 is 12.
Answer:
3/4
Step-by-step explanation:
3/14 ÷ 2⁄7
Copy dot flip
3/14 * 7/2
We rewrite
3/2 * 7/14
Canceling a 7 from 7 and 14
3/2 * 1/2
Multiplying straight across
3*1 =3
2*2=4
3/4
