One may note you're kinda missing the factors provided, but anyhow, it factors to

$\bf 3a^2+6a-2a-4\implies (3a^2+6a)-(2a+4)
\\\\\\
3a(a+2)~~-~~2(a+2)\implies \stackrel{common~factor}{(a+2)}[3a-2]$

What is the perimeter of triangle DEF

LuckyWell [14K]

Remember that A squared plus B squared equals C squared.

Since sides F_D and D_E are both 3, the answer cannot be 4.2 or 2.4.

SO basically you just add 3 + 3 = (The side F_E, which you can get by putting numbers in the formula), you should get your answer.

3² + 3² = Line EF²
9 + 9 = Line EF²
18 = Line EF²
√18

You get the idea. Hope this helps!

1. Find Angle A :

$x + 24 = 3x$

$3x - x = 2 4$

$2x = 24$

$x = 12$

Angle A :

$3x$

$3 \times 12$

$36 \degree$

2. Find Angle B :

$10x - 27 = 7x$

$10x - 7x = 27$

$3x = 27$

$x = 9$

Angle B :

$10x - 27$

$(10 \times 9) - 27$

$90 - 27$

$63 \degree$

Find Angle C :

$5x + 1 = 6x - 13$

$6x - 5 x = 1 + 13$

$x = 14$

Angle C :

$5x + 1$

$(5 \times 14) + 1$

$70 + 1$

$71 \degree$

Find Angle D :

$6x + 3 = 4x + 39$

$6x - 4x = 39 - 3$

$2x = 36$

$x = 18$

Angle D :

$4x + 39$

$(4 \times 18) + 39$

$72 + 39$

$111\degree$

And it's given :

36° = Angle A = B

63° = Angle B = A

71° = Angle C = H

111° = Angle D = E

Therefore, the answer will be " BAHE "

Wade and Alexandra are 240 feet apart when they start walking toward one another. Alexandra walks twice as fast as Wade so whene

Cerrena [4.2K]

Answer:

The initial distance between Wade and Alexandra is 240ft.

They walk towards each other.

Alexandra walks twice as fast as Wade.

Now, because they are walking towards each other, when the distance walked by both of them equals 240 ft, they will meet.

Then:

if Wade walks z ft, Alexandra walks 2*z ft.

So we have the equation:

Distance that Wade walked + Distance that Alexandra walked = 240ft

z + 2*z = 240ft

3*z = 240ft

z = 240ft/3 = 80ft

They will meet when Wade walks 80ft.
