PLEASE ANSWER FASTConstruct ΔABC with AB = 3.8 cm, BC = 4.5 cm and CA = 5 cm.

Step-by-step explanation:

I will write the steps of construction,

1. Draw line segment BC = 4.5cm

2.Using a compass and radius 3.8 cm draw an arc

keeping the point at B.

3.Again taking the radius as 5cm draw an another arc intersecting the previous arc.

4. Join both the lines at that arc and you will get

Triangle ABC.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
