Answer:
x = -3
Step-by-step explanation:
-7X + 6= 27
Subtract 6 from each side
-7x +6-6 = 27 -6
-7x = 21
divide each side by -7
-7x/-7 = 21/-7
x = -3
Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2
1.) (-4,0).....x1 = -4 and y1 = 0
(4,6)......x2 = 4 and y2 = 6
now sub into the formula...
d = sqrt ((4 - (-4)^2 + (6 - 0)^2)
d = sqrt ((4 + 4)^2 + (6^2))
d = sqrt (8^2 + 6^2)
d = sqrt (64 + 36)
d = sqrt 100
d = 10 <=====
u would use the exact same formula for the rest of these problems
2.) (5,7),(0,-5)......distance is : 13
3.) (2,-1),(1,-4).....distance is : 3.16
4.) (-7,-2),(0,7).....distance = 11.4
Answer:
4
Step-by-step explanation:
the side Q-R corresponds to K-L
just as O-P corresponds to K-J
K-J= 36
O-P=6
36/6=6
so 24/6=4
Answer:
C
Step-by-step explanation:
Any number with a 0 at the end is divisible by 10
Answer:
Correct choice is C). mn=ac
Step-by-step explanation:
Given statement is that the first step in factoring a trinomial of the form is to find two numbers, m and n, such that m + n = b and _____.
We know that when we factor polynomial of type ,product of both numbers m and n must be same as product of a and c.
Hence correct choice is C). mn=ac
