Can you put a number for I can know which question you answered?

The first one is y= 2

The second is y=4

The third one is y=4

The last one is y=2

Step-by-step explanation:

The easiest way to solve these types of problems is to Subsititute.

1) Givens: x=1; y=2x

Substitute

y=2

2) givens: x=2 y=2x

Substitute

y=4

3) Givens: x=-4; y=-2x-4

Substitute

y=4

4) givens: x=-3; y-2x-4

Substitute

y=2

Hope this helped :)

1.) y=2

2.) y=4

3.) y=4

4.) y=-2

Step-by-step explanation:

1.) y=2x Multiply 1*2. y=2

2.) do the same thing. 2*2. y=4.

3.) plug in the x value and do order of operations. y= 2(-4)-4. y=4.

4.) plug in your values again. y= -2(-3)-4. y= -2.

hope this helps!!

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
