Answer:
A. 4(4a + 18)
B. 8(2a + 9)
Step-by-step explanation:
<u><em>We know that</em></u> :
16a = 4×4×a
72 = 4×18
Then
16a + 72 = 4×(4a) + 4×(18)
= 4 × (4a + 18)
On the other hand,
16a = 8×2×a
72 = 8×9
Then
16a + 72 = 8×(2a) + 8×(9)
= 8 × (2a + 9)
Could you get a closer picture?
3.5 is the IQR of <span>0,1,1,3,3,3,4,5, and 7</span>
4(4x)+(x)
= 16x+x
Combine like terms
16x+x
(16x+x)
= 17x
x=17
I hope that's help ! Good night .
Answer:
x = 9.6
Step-by-step explanation:
9x + 1 = 88
combine like terms
9x = 87
