Simplify the following expression : 2 (2x-3)+5 (6x+1)

vivado [14]

To simplify begin by distributing the multiplication outside the parenthesis:
$2(2x-3)+5(6x+1) =4x-6+30x+6 \\ 4x+30x=34x$

Please helpppppp mee thanks everyone

Answer:

$\frac{32}{35}$

Step-by-step explanation:

To answer this question you need to get the same denominator (bottom number of a fraction ) on both values

Because 7 is a factor of 35, you can multiply the whole fraction by 5, (so that the first fraction has a denominator of 35 which is the same as the other value)

$\frac{4}{7}$ ×5 $= \frac{20}{35}$

then you add them up but remember if the denominator is the same you do <u>not </u> add them.

$\frac{20}{35} +\frac{12}{35} = \frac{32}{35}$

Hope the answer is right, Ask if unsure :)

Ethan is 1.85 meters tall. At 10 a.m., he measures the length of a tree's shadow to be 28.45 meters. He stands 24.3 meters away

ser-zykov [4K]

Answer:

Height is 12.68 m

Step-by-step explanation:

• Consider triangle formed by Ethan's head, Ethan's feet and shadow's tip

opposite = 1.85 m
hypotenuse = x
adjacent = (28.45 - 24.3) = 4.15 m

• From pythogras theorem:

${ \rm{a {}^{2} + {b}^{2} = {c}^{2} }} \\ { \rm{ {4.15}^{2} + {1.85}^{2} = {x}^{2} }} \\ { \rm{ {x}^{2} = 20.645}} \\ { \rm{x = 4.54}} \\ { \rm{hypotenuse = 4.54 \: m}}$

• From scale factors:

${ \rm{ \frac{28.45}{4.15} = \frac{h}{1.85} }} \\ \\ { \rm{h = \frac{1.85 \times 28.45}{4.15} }} \\ \\ h = 12.68 \: m$
