Answer:

ga = 14

gb = 17

Explanation:

It's just simply replacing the empty spaces (let's call those x) and doing the necessary operations. If I gave you T = 10 + x, T would be equal to 10x. Similarly, in the first problem we replace x with the given number g and then do all our operations (T = 10 + g(4)), in the second one, we also have to remember that the formula to calculate T is T = 10 + g. Knowing that, we replace the first blank (y) with 10, and the second blank with our given number g. I hope you do well :D

A triangle T is bounded (on three sides) by the lines x = 6, y = 0, and y = 3 2 x. A rectangle of width w is inscribed inside T.
Viktor [21]

Answer:

33.85 units^2

Step-by-step explanation:

you must first draw the triangle on the plane using the equations (see

attached file), you will have a right angle triangle with a height of 192 and a base of 6.

then you calculate the angle with the tangent function = 88.21

Then you use the small triangle to find the value of a (see attached file).

Finally, you propose an equation for X to find one of the sides of the triangle, once you have x squared it, and you already have the area,

The sum of two numbers, x and y, is 12. The difference of x and two times y is 6. What are the values of x and y?
LekaFEV [45]
Hey,
It is given that x+y=12 and,
x-2y=6
Therefore the value of x & y will be
x+y=12
-x+2y=6 (Changing signs)
--------------
0+3y=6
--------------
=> 3y=6
=>y=6/3
=>y=2
To find value of x ,
x+y=12
x=12-2
x=10
Therefore , value of x=10 and y=2
( option=>B.)
Hope this helps you....
