The height of a rectangle is multiplied by 4. which of the following describes the effect of this change on the area?
the area is multiplied by 16.
the area is multiplied by 8.
the area is multiplied by 4.
the area is multiplied by 2.

Area is multiplied by 4.

Step-by-step explanation:

The area of rectangle with dimensions h and l are h*l.

If we multiply the height,h, by 4 we get the dimensions are 4h and l, and so the new area would be (4h)*l or 4hl or 4(hl).  So the area would be 4 times as much as it was before.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
