Answer:
Step-by-step explanation:
6) triangle ABC is similar to triangle DEC. It means that
AB/DE = BC/EC = AC/DC
Therefore,
6/21 = 10/y
Cross multiplying, it becomes
6y = 210
y = 210/6
y = 35
Also
6/21 = x/28
Cross multiplying, it becomes
6 × 28 = 21x
21x = 168
x = 168/21
x = 8
7) triangle JKL is similar to triangle NMP. It means that
JK/NM = KL/MP = JL/NP
Therefore,
49/14 = (9x + 1)/(x + 5)
Cross multiplying, it becomes
49(x + 5) = 14(9x + 1)
49x + 245 = 126x + 14
126x - 49x = 245 - 14
77x = 231
x = 231/77
x = 3
For the answer to the question above, I'll provide my solutions below.
x² + 4 = 0
<span> - 4 - 4
</span> x² = -4
x = +2i
x² - 6x + 1 = 0
x = -(-6) +/- √((-6)² - 4(1)(1))
2(1)
x = 6 +/- √(36 - 4)
2
x = <span>6 +/- √(32)
</span> 2
x = <span>6 +/- 2√(2)
</span> 2
x = 3 + √(2)
x = 3 + √(2) x = 3 - √(2)
I hope this helps.

The dimension of the rectangular box is 60cm x 45cm x 32cm. The dimension of the wood used has the thickness of 2.5 cm all around the rectangular box. In order to get the volume of the wood, subtract each side of the rectangular box by 2.5.
Volume = 57.5 cm x 52.5cm x 29.5cm
Volume = 89053.1252 cm^3
