Answer:

Area = .75 $\sqrt{5}$

Step-by-step explanation:

$Height = \sqrt{2.5^{2} - 1.5^{2} }$

$Height = \sqrt{6.25 - 1.25}$

$Height = \sqrt{5}$

Area = 1.5( $\sqrt{5}$ )/2

Area = .75 $\sqrt{5}$

(5+6b^3)^2 expand and combine like terms

Drupady [299]

Answer:

$( 5 + 6b^3)^2 = 36b^6 + 60b^3 + 25$

Step-by-step explanation:

$(a + b)^2 = a^2 + b^2 + 2ab$

So,

$(5 + 6b^3)^2 = (5)^2 + (6b^3)^2 + 2 (5)(6b^3)$

$= 25 + 36b^6 + 60b^3$

I’m confused please help

Law Incorporation [45]

So x equals 30 because u did 180-150 and y is also 30 since you found x you then add 90 plus 30 and it will give u 120 then 180 minus 120 will be 60 then 90 - 60 because u are trying to find y, and u will get 30.

It costs $3.45 to buy 3/4 lb of chopped walnuts. How much would it cost to purchase 12 lbs of walnuts? Enter the numeric value o

mote1985 [20]

Answer:

$55.20

Step-by-step explanation:

Create a proportion where x is the cost of 12 lbs of walnuts:

$\frac{3.45}{0.75}$ = $\frac{x}{12}$

Cross multiply and solve for x:

0.75x = 41.4

x = 55.2

So, for 12 lbs of walnuts, it will cost $55.20
