Please help me find how to solve . The area of one is 196 with a side length of 21 in , the other has a side length of 15in

Area =100 in^2

Step-by-step explanation:

scale factor of the triangles is :15/21=5/7

if two similar shape has a scale factor a/b then the area is a^2:b^2

area of first shape/area of second shape=5/7

x/196=(5)²/(7)²

49x=4900

x=4900/49=100

area=100

check: 100/196=25/49=a^2/b^2

i hope it is right

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
