Answer:
11.2
Step-by-step explanation:
If the rectangulars are similar then we can use similarity ratio to calculate value of x
CD is similar to RS and AB is similar to QP
4/6.4 = 7/x cross multiply expressions
4x = 44.8 divide both sides by 4
x = 11.2
Answer:
The expression represents the number rewritten in a+bi form.
Step-by-step explanation:
The value of is in term of
Substituting the value,
Product of two negative numbers is always positive.
Now in term of
Substituting the value,
Product of one negative and one positive numbers is always negative.
Now can be written as follows,

Answer:
1/2
Step-by-step explanation:
(y2-y1)/(x2-x1) is the equation for finding slope with two given points
-5-(-2) over 3-9 equals
-3/-6=-1/-2=1/2
The equation of this line in slope intercept form is y= 3/7x
