X=5.4 because that is how i figured out the answer and I didn’t even figure out
Answer:
ABCD and EFGH
ABCD and PQRS (or EFGH and PQRS)
Dilate by a scale factor of 3
Step-by-step explanation:
Congruent means they have the same shape and size.
Similar means they have the same shape, but not necessarily the same size.
The orientation (rotation angle) or position do not matter.
EFGH is reflected and rotated, so it maintains the same shape and size as ABCD. Therefore, they are congruent.
PQRS is scaled and translated, so it has the same shape, but different size than ABCD. Therefore, they are similar but not congruent.
Also, PQRS is similar to EFGH, but not congruent.
To make EFGH congruent to PQRS, we need to make it the same size. So we need to scale EFGH by a factor of 3.
The number is 24. If 8 is one third of the number, you multiply 8 by 3 to find the number, which is 24.
Answer:
Step-by-step explanation:
First expand the expression so you know the coefficients of x and y.
4(2x+y+2y) = 4(2x+3y) = 8x+12y
8x+12y = 8x+12y
6x+7y ≠ 6x+12y
8x+y+2y = 8x + 3y ≠ 8x+12y
8x+4y+8y = 8x+12y = 8x+12y
−<span>2.8
</span>Okay so "0.9x-1.3=-3.1" x=-2
<span><span><span>0.9x</span>−1.3</span>=<span>−3.1
</span></span>add 1.3 to both sides
<span><span><span><span>0.9x</span>−1.3</span>+1.3</span>=<span><span>−3.1</span>+1.3
</span></span><span><span>0.9x</span>=<span>−1.8
</span></span>divide both sides by 0.9
<span><span><span>0.9x/</span>0.9</span>=<span><span>−1.8/</span><span>0.9
</span></span></span>x=<span>−2</span>
So if you plug in -2 into "x-0.8" you get −2.8
<span>=<span><span>−2</span>−0.8
</span></span><span>=<span><span>−2-</span><span>0.8
</span></span></span><span>=<span>−2.8
</span></span>Hope this helps.
