Answer: Found it by web and solving
Step-by-step explanation: L = W + 4
LW = 60
---
LW = 60
(W + 4)W = 60
W^2 + 4W + (-60) = 0
---
above is in quadratic equation form: ax^2 + bx + c = 0
---
use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a
---
the two solutions are:
W = 6
W = -10
the negative solution doesn't make sense for length, so use the positive solution.
---
L = 10
W = 6
The answer is B because facts
Answer:
×=3
Step-by-step explanation:
3× + × + 8 = 20
4×= 12
divide 4 with 12 and it will be 3
Answer:
34 degrees
Step-by-step explanation:
I love this unit a-lot (super fun)
So Congruent/Congruence is, For example If you have two triangles on a coordinates grid with the same coordinates than that would mean they're congruent. Shortened down would be
Same shape same coordinates same dimension same size (same everything)
Transformations would be Rotating a shape clockwise(CW)...right) or counterclockwise(CC Left)
Or Dilation which is making the shape smaller or bigger based on a scale factor.
Or reflection
How you would perform Reflection is reflect the shape over either the X-axis
Or the Y-axis
How you would perform a Translation would be to literally move the shape right left up or down.
How you would perform a Dilation(scaling) would be to pick a scale factor and either decrease or increase the size of the shape according to the scale factor number
How you would perform a Rotation would be to pick a point of rotation (P.O.R) and then pick your measure º such as 90º clockwise and rotate accordingly.
Hope it helps :)
