Pls help I don’t understand I’ll give brainliest

Aloiza [94]

Answer:

$- 32$

Step-by-step explanation:

1) Simplify

$\sqrt{32} \: to \: 4 \sqrt{2}$

$- 8 \sqrt{2} \times \frac{1}{2} \times 4 \sqrt{2}$

2) Use this formula: a/b × c/d = ac/bd.

$- \frac{8 \sqrt{2} \times 1 \times 4 \sqrt{2} }{2}$

3) Simplify.

$- \frac{32 \sqrt{2 \sqrt{2} } }{2}$

$simplify \: 32 \sqrt{2 } \sqrt{2} \: to \: 32 \sqrt{4}$

5) Since 2 × 2 = 4, the square root of 4 is 2.

$- \frac{32 \times 2}{2}$

6) Simplify 32 × 2 to 64.

$- \frac{64}{2}$

7) Simplify 64/2 to 32.

$- 32$

Therefor, the answer is option three -32

MATRECIES: Suppose ={u,v,w}⊆R3 is linearly independent. Determine if the set 4 ={u, v, v−w, u+v+w} is linearly independent or li

AlladinOne [14]

The set is linearly dependent.

To explicitly prove this, we need to show there is at least one choice of constants $c_1,c_2,c_3,c_3\in\Bbb R$ such that

$c_1 u + c_2 v + c_3(v-w) + c_4(u+v+w) = 0$

or equivalently,

$(c_1 + c_4) u + (c_2 + c_3 + c_4) v + (-c_3 + c_4) w = 0$

which is the same as solving the system of equations

$\begin{cases} c_1 + c_4 = 0 \\ c_2 + c_3 + c_4 = 0 \\ -c_3 + c_4 = 0 \end{cases}$

From the first and last equations, we have $c_1=-c_4$ and $c_3=c_4$ . Substituting these into the second equation leaves us with $c_2-2c_1=0$ , and so the overall solution set is

$c_1 = \dfrac12 c_2 = -c_3 = -c_4$

for which there are infinitely many not-all-zero solutions.

The number of states that joined the United States between 1776 and 1849 is twice the number of states that joined between 1850

AlexFokin [52]

Answer: b. 2x = 30

Step-by-step explanation:

Given : 30 states joined the United States between 1776 and 1849

and x states joined between 1850 and 1900 .

If the number of states that joined the United States between 1776 and 1849 is twice the number of states that joined between 1850 and 1900.

i.e. No. of states joined the United States between 1776 and 1849= 2 (No. of states that joined between 1850 and 1900)

i.e . 30= 2(x) [Substitute the values]

i.e . 2x=30

Hence, the true equation : 2x=30
