∑ Hey, microhiezv ⊃

Answer:

n = -3/7    - Fraction Form

n = -0.43 - Decimal Form

Step-by-step explanation:

<u><em>Given:</em></u>

5n - 2 ( 2 -n ) = -7

<u><em>Solve:</em></u>

5n-2\left(2-n\right)=-7

Distribute -  5n - 2 ( 2 - n ) : 7n - 4

7n-4=-7

Add 4 to both sides:

7n-4+4=-7+4

7n = -3

Divide both sides by 7

\frac{7n}{7}=\frac{-3}{7}

n=-\frac{3}{7}

n=-0.43

Find the surface area of the composite solid.
Westkost [7]

We have:

4 triangles with the base b = 5ft and the height h = 6ft

4 rectangles with the lenght l = 5ft and the width w = 4ft

1 square with side a = 5ft.

The formula of an area of a riangle:

A_T=\dfrac{1}{2}bh

Substitute:

A_T=\dfrac{1}{2}(5)(6)=\dfrac{1}{2}(30)=15\ ft^2

The formula of an area of a rectangle:

A_R=lw

Substitute:

A_R=(5)(4)=20\ ft^2

The formula of an area of a square:

A_S=a^2

Substitute:

A_S=5^2=25\ ft^2

The Surface Area of composite solid:

SA=4A_T+4A_R+A_S

Substitute:

SA=4(15)+4(20)+25=60+80+25=165\ ft^2

<h3>Answer: The Surface Area of the composite solid is 165 ft².</h3>

Please I need help with this question: 2 + 2d &gt; 6
Aleonysh [2.5K]

d > 2

Step-by-step explanation:

1) Subtract 2 from both sides.

2d > 6 - 2

2) Simplify 6 - 2 to 4.

2d > 4

3) Divide both sides by 2.

d >  \frac{4}{2}

4) Simplify 4/2 to 2.

d  > 2

Therefor, the answer is, d >2.

Determine the slope-intercept form of the equation of the line parallel to y = x + 11 that passes through the point (–6, 2).
MArishka [77]
Line parallel to y=x+11 so slopes are equal then
y= x+b
Passing through the point C (-6;2) then C belongs to this line
yc=xc+b
b= 6+2
b= 8
So y intercept is equal to 8
