Answer:

$\text{The product is -45+18x}$

Step-by-step explanation:

Given the expression

$-9(5-2x)$

we have to find the product.

$-9(5-2x)$

By distributive property,

$a(b+c)=ab+ac$

$\text{Put a=-9, b=5 and c=-2x}$

$-9(5+(-2x))=-9(5)+(-9)(-2x)=-45+18x$

which is the required product.

Solve the triangle for all missing sides and angles

Mama L [17]

Answer:

x = 35

C = 18.92

A = 71.07

Step-by-step explanation:

Use the Pythagorean theorem to find the unknown side.

$a^{2} +b^{2} =c^{2} \\\\\\12^{2} +x^{2} =37^{2} \\x^{2} = 37^{2}-12^{2}\\x=35$

For Angle C

The angle C can be found using the inverse sine function.

C=arcsin(opp/hyp)

C=arcsin(12/37)

C=18.92

For Angle A

The sum of all the angles in a triangle is 180 degrees.

A + 90 + 18.92 = 180

A = 71.07

a)b 256What are the values of a and b in the equation(4x[4x2- ?○ a-2, b-4○ a=-2, b-4○ a-2, b=-4○ a-2, b=-422aaaa0000C日

klasskru [66]

Hi.... your answer is below:

$\left( 4.x^{a} \right)^{b}=\dfrac{256}{x^{8}}\rightarrow 4^{b}x^{ab}=256x^{-8}\rightarrow 2^{2b}.\,x^{ab}=2^{8}.\,x^{-8}\rightarrow\\ \text{by comparison}\\ 2^{2b}=2^{8}\rightarrow 2b=8\rightarrow \boxed{b=4}\\ x^{ab}=x^{-8}\rightarrow x^{4a}=x^{-8}\rightarrow 4a=-8\rightarrow \boxed{a=-2}$

Thanks....

Marcus looked up the path that he had taken on his run this morning on the map shown below.

AURORKA [14]

Answer: 6 miles.

Step-by-step explanation:

1. To solve this problem you only need to add the distances shown in the map attached, which shown the path Marcus had taken. Then, you have:

$Total_{distance}=1in+3inches+2inches+2.3inches\\Total_{distance}=8.3inches$

2. Now, you must convert the result obtained from inches to miles. According to the problem $4inches=3miles$ , therefore, you have:

$Total_{distance}=\frac{8,3inches*3miles}{4inches}\\Total_{distance}=6.22miles$

3. To the nearest mile:

$Total_{distance}=6miles$
