I don’t really know where the blue dot is
You know that all of the triangles are congruent, so you only have to find the area of one and then multiply it by four. So you would multiply 5 by 7 and get 35. The divide that my two to get 17.5, which is the area of the triangles. Then you would multiply that by four and get 140, which is the area of the figure
(a) it is always true -5.2 x ( -1.4 ) =7.28 AND -1.4 x (-3.6) =5.04
(b)the rule for multiplying negatives is negative x negative = positive.
i hope i answered what you where asking
Answer:
Step-by-step explanation:
Joint variations occurs when one variable depends on the value of two or more variables. The variable varies directly or indirectly with the other variables combined together. The other variables are held constant. From the given examples, the equation(s) that represent joint variations are
1) z = 3x/y
z varies directly with x and inversely with y.
2) w = abc/4
w varies inversely with a,b and c. 4 is the value of the constant of variation.
