Step-by-step explanation:
Ruthie wants to construct a line that passes through point P and is perpendicular to AB. What should Ruthie do first?
A) measure the length of segment AB with her compass
B) construct two intersecting arcs with centers A and B
C) use her straight-edge to draw a line from point P to point A
☆☆☆D) construct an arc with center P that intersects segment AB in two points
Answer:
D) c - 2 = 25 + c + 10√c
Step-by-step explanation:
The given equation is 
Taking square on both sides, we get
Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.
c - 2 = 5^2 + (√c)^2 + 2(5)√c
c - 2 = 25 + c +10√c
Answer: D) c - 2 = 25 + c + 10√c
Thank you.
Answer:
x = 3 and y = 7
Step-by-step explanation:
Given that,
8x+3y=45 .......(1)
2x+3y=27 ........(2)
We need to solve equations (1) and (2)
Multiply equation (2) by 4.
8x+12y=108 .....(3)
Subtract equation (1) from (3).
8x+12y-(8x+3y)=108-45
12y-3y = 63
9y = 63
y = 7
Put the value of y in equation (1).
2x+3(7)=27
2x+21 = 27
2x = 27-21
2x = 6
x = 3
So, the values of x and y are 3 and 7 respectively.
Number 2 is 990 because the numbers are 9, 10, and 11.
