3x+21 or 3x+3(7)
You distribute the 3 to all numbers
Hey there!
For this problem, we just want to combine out like terms. A like term in this situation are terms with different (or they can be the same) coefficients to the variable, but with the same variable.
As we can see, that means two of our terms, and one will have to be left in its original form because it has no other like term. That term is the -4d.
If we combine the -2c + 3c, we get:
-4d + c
Hope this helps!
Answer: 20
Step-by-step explanation:
37 - 17 = 20
20 + 17 = 37
Cos 52 = 0.6157
sin 42 = cos 48 = 2/3 (because 42 + 38 = 90 - complementary angles)
if tan 20,5 = 3/8 then tan 69.5 wil = 1 / 3/8 = 8/3
Answer:
C. There is no error. This is a correct conclusion.
Step-by-step explanation:
Reflection is a transformation in which a given image is flipped across a reflection line to create the image. Each point of the image (e.g ONML) maintained their distance from the line as the initial object (e.g OPQR). The size of the object and image are the same after a reflection.
Dilation involve resizing the dimensions of a given object to produce an image of the same shape. It requires a scale factor to either increase or decrease the dimensions of the object.
Comparing quadrilaterals OPQR and ONML. Drawing a reflection line vertically through O, it can be observed that OPQR was first reflected. Then enlarged by a scale factor to produce ONML, thus dilation.
Therefore, there is no error in Bastian's conclusion.
