Find the simplified product 2 square root 5x^3(-3 square root 10x^2
Ivanshal [37]

The simplified product of 2\sqrt{5x^{3} } and -3\sqrt{10x^{2} } is -30x^{5/2} \sqrt{2}.

Given Two expressions: -3\sqrt{10x^{2} } and 2\sqrt{5x^{3} }.

We have to multiply both the expressions and it can be done as under:

-3\sqrt{10x^{2} } *2\sqrt{5x^{3} }

Firstly we have to multiply -3 with 2 to get

=-6\sqrt{10x^{2} }\sqrt{5x^{3} }

Then we have to find square root of x cube and x square which is x to the power 3/2 and x to the power 1.

=-6x^{3/2} x\sqrt{10}\sqrt{5}

Now we have to multiply both the numbers in the root to get the answer;

=-6x^{5/2} \sqrt{50}

Square root of 50 is 5 root 2.

=-6*5\sqrt{2}x^{5/2}

=-30\sqrt{2}x^{5/2}

Hence the simplified product is -30\sqrt{2}x^{5/2}.

A and B are complementary angles. If m_A = (6x + 29) and m
Liono4ka [1.6K]

Answer:

m∠A=77°

Step-by-step explanation:

Complementary angles are a pair of angles whose measures have a sum of 90°. Since m∠A = 6x+29 and m∠B = x+5, we can write the following equation to solve for x:

6x+29+x+5=90

Solving for x, we get:

6x+29+x+5=90

7x+34=90 (Simplify LHS)

7x+34-34=90-34 (Subtract 34 from both sides of the equation to isolate x)

7x=56 (Simplify)

\frac{7x}{7}=\frac{56}{7} (Divide both sides of the equation by 7 to get rid of x's coefficient)

x=8

Therefore, m∠A=6x+29=6(8)+29=48+29=77°. Hope this helps!

A seller has a house that is 1700 ft^2. The neighborhood comps show the line of best fit to be y=0.074x + 50.48. What is a fair
natita [175]
Let the price for the house be x and the square feet of the house be y,
when the house is 1700 sq ft, y = 1700.

y = 0.074x + 50.48
1700 = 0.074x + 50.48
0.074x = 1700 - 50.48
0.074x = 1649.52
x = 22 290.81 (to the nearest cent)

A fair price for this house would be $22 290.81.
