Answer:
<em>m∠1 = 98°</em>
Step-by-step explanation:
Answer:
I think its A & B
Two Squares with the same side lengths are always congruent and Two rectangles with the same side lengths are always congruent.
Move all terms to one side
4w^2 + 49 + 28w = 0
Rewrite 4w^2 + 49 + 28w in the form a^2 + 2ab + b^2, where a = 2w and b = 7
(2w)^2 + 2(2w)(7) + 7^2 = 0
Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2
(2w + 7)^2 = 0
Take the square root of both sides
3w + 7 = 0
Subtract 7 from both sides
2w = -7
Divide both sides by 2
<u>w = -7/2</u>
Answer:
Gradient = 2
Step-by-step explanation:
Gradient of a line = Slope of the line
Since, slope of a line passing through two points 
and 
is given by,
Slope = 
Given line in the graph passes through two points (1, 0) and (2, 2)
Therefore, slope or gradient of the line = 
= 2
Gradient = 2 will be the answer.
For this question, the equation I got was (x+3)^2 + (y-6)^2 = r^2.
