Rewrite without parentheses and simplify. (y+7)^2

2 answers:

5 0

(y + 7)^2 = (y + 7)(y + 7)

Multiply all the terms in the first parenthesis to all the terms in the 2nd parenthesis:

y * y = y^2
y * 7 = 7y
7 * y = 7y
7 * 7 = 49

So we have:

y^2 + 7y + 7y + 49

Combine like terms:

y^2 + 14y + 49

Given ΔKLM with lengths as marked, what is the relationship of segment NO to segment KL?

Oliga [24]

Segment NO is parallel to the segment KL.

Solution:

Given KLM is a triangle.

MN = NK and MO = OL

It clearly shows that NO is the mid-segment of ΔKLM.

By mid-segment theorem,

<em>The segment connecting two points of the triangle is parallel to the third side and is half of that side.</em>

⇒ NO || KL and $NO = \frac{1}{2}KL$

Therefore segment NO is parallel to the segment KL.

You purchase a car in 2010 for $25,000. The value of the car decreases by 14% annually. What would the value of the car be in 20

Fed [463]

Answer: -$6,500

Step-by-step explanation:

Here we could , use the arithmetic progression where

T(2020 - 2010) = a + ( n - 1 )d

T10 = a + ( 10 - 1 )d --------------- 1

a = $25,000, n = 10 and d = 14% of $25,000 = $3,500 the common difference.

Note since it decreases the common difference d = -$3,500.

Now substitute for the values in the equation above.

T10 = 25,000 + 9 x -3,500

= $25,000 - $31,500

= -$6,500 (deficit )

-2v3 + v75

Lena [83]

Answer:

a) $3\sqrt{3}$

Step-by-step explanation:

Step(i):-

Given - 2 √3 + √75

we know that 25 × 3 = 75

- 2 √3 + √75

= -2 √3 + $\sqrt{25 X 3}$

By using

$\sqrt{ab} = \sqrt{a} \sqrt{b}$

= $-2\sqrt{3} + \sqrt{25} X \sqrt{3}$

= $-2\sqrt{3} + 5 \sqrt{3}$

= $(-2 + 5 ) \sqrt{3}$

= $3\sqrt{3}$
