Answer:
−1 ≤ n + 7 < 9
To solve a compound inequality separate it into two inequalities
That is
n + 7 ≥ - 1 and
n + 7 < 9
Solve the inequality
n + 7 ≥ -1
n ≥ - 8
and
n + 7 < 9
n < 7 - 9
n < 2
Find the intersection
The final answer is
-8 ≤ n < 2
Hope this helps
Answer:
h=9cm
P=(x+5)cm
b=(x-3)cm
by the Pythagoras theorem,
h^2=p^2+b^2
9^2=(x+5)^2+(x-3)^2
81=x^2+10x+25+x^2-6x+9
81=2x^2+4x+34
1 <span>Set up the long multiplication.
</span>
<span><span>543</span><span>x36</span></span>
2 <span>Calculate 3 x 6, which is 18.
Since 18 is two-digit, we carry the first digit 1 to the next column.
</span>
3 <span>Calculate 4 x 6, which is 24. Now add the carry digit of 1, which is 25.
Since 25 is two-digit, we carry the first digit 2 to the next column.
</span>
4 <span>Calculate 5 x 6, which is 30. Now add the carry digit of 2, which is 32.
Since 32 is two-digit, we carry the first digit 3 to the next column.
</span>
5 <span>Bring down the carry digit of 3.
</span>
6 <span>Calculate 3 x 3, which is 9.
</span>
7 <span>Calculate 4 x 3, which is 12.
Since 12 is two-digit, we carry the first digit 1 to the next column.
</span>
8 <span>Calculate 5 x 3, which is 15. Now add the carry digit of 1, which is 16.
Since 16 is two-digit, we carry the first digit 1 to the next column.
</span>
9 <span>Bring down the carry digit of 1.
</span>
10 <span>Calculate 3258 + 16290, which is 19548
</span>
11 <span>Therefore, 543 x 36 = 19548.
