7 0
This is an isosceles triangle: a triangle with two sides equals.
Therefore:
side BA=side CA
8x-4=5x+11

8x-5x=11+4
3x=15
x=15/3
x=5

length of  side BC=4x-2=4(5)-2=20-2=18.

The lenght of side BC is 18 units of lenth.

Every economic decision has only positive benefits. gained opportunities. unavoidable limitations. a consequence or tradeoff.
Alina [70]
Every economic decision has "a consequence or tradeoff" - this final answer choice is correct. Every time that an individual, business, or institution makes an economic decision, they always forgo an opportunity to use the same capital or resources for other endeavors. As such, there is a tradeoff incurred by not making the decision to use the resource in another manner. This is known as opportunity cost and is one of the fundamental tenets of economic theory.

2. Solve the following system of equations using substitution.
SOVA2 [1]
First, make sure you convert both equations into standard form. Your two equations would be 2x+2y=38 and -x+y=3. Then multiply the bottom by 2. So your new equations would be 2x+2y=38 and -2x+2y=6. The x would cancel out and you would continue solving for y. y would equal 11 and then you would plug it back into an original equation. When you plug and solve for x, you would get x=8. So your answer would be (8,11)

Please help me with this question
Setler [38]

Step-by-step explanation:

{ ({y}^{2} )}^{4} . \:  {( {y}^{3}) }^{2}

Since,

{ ({a}^{x} )}^{y}  =  {a}^{xy}

Hence,

{y}^{2 \times 4} . {y}^{3 \times 2}

=  {y}^{8} . {y}^{6}

Since,

{a}^{x} . {a}^{y}  =  {a}^{x + y}

Hence,

=  {y}^{8 + 6}

=  {y}^{14} (ans)
