Given:
edge 1 = 3x - 4
edge 2 = x² - 1
edge 3 = 2x² - 15

perimeter if x = 4

edge 1 = 3(4) - 4 = 12 - 4 = 8
edge 2 = 4² - 1 = 16 - 1 = 15
edge 3 = 2(4²) - 15 = 2(16) - 15 = 32 - 15 = 17

Perimeter = 8 + 15 + 17 = 40 feet.

Make 2xy+6y=10 into a y=
Naily [24]

Answer:

The value of y in the given equation is \frac{5}{x+3}

Therefore y=\frac{5}{x+3}

Step-by-step explanation:

Given equation is 2xy+6y=10

We have find the value of y in the given equation :

2xy+6y=10

Taking the common term 2y outside of LHS we get

2y(x+3)=10

Multiplying by \frac{1}{2}  on both sides

2y(x+3)\times \frac{1}{2}=10\times \frac{1}{2}

y(x+3)=5

Dividing by x+3 on both sides we get

\frac{y(x+3)}{x+3}=\frac{5}{x+3}

y=\frac{5}{x+3}

Therefore the value of y in the given equation is \frac{5}{x+3}

Therefore y=\frac{5}{x+3}

What is the exact circumference of a circle with a radius of 17 mm?
inn [45]
<h3>The exact circumference of a circle with a radius of 17 mm is 34 \pi or 106.76 mm</h3>

<em><u>Solution:</u></em>

Given that,

A circle with radius 17 mm

To find: circumference of circle

<em><u>The circumference of circle is given as:</u></em>

C = 2 \pi r

Where, "r" is the radius of circle

<em><u>Substitute r = 17 mm</u></em>

C = 2 \times \pi \times 17\\\\C = 34\ \pi\\\\C = 34 \times 3.14\\\\C = 106.76

Thus the exact circumference of a circle with a radius of 17 mm is 34 \pi or 106.76 mm

A*4=e b\4=e c+4=e d-4=e A+b+c+d=100
ratelena [41]
I believed you are looking for the value of e. The value of e is 16 below is the solution:

A×4 = E, so A=E/4
B/4 = E, so B=4E
C+4 = E, so C=E=4
D-4 = E, so D=E+4
and
A+B+C+D=100.

Substitute values of A, B, C and D in the equation, we get,
(E/4) + 4E + E-4 + E+4 = 100
(E/4) + 4E + 2E = 100
(E/4) + 6E = 100
(E+24E)/4 = 100
E+24E = 100×4
25E = 400
E = 400/25
