Answer:
8x² - 14x - 15
Step-by-step explanation:
(4x + 3)(2x - 5)
8x² - 20x + 6x - 15
8x² - 14x - 15
Answer:
26
Step-by-step explanation:
if you convert 0.26 into a fraction you get 26/100 so the answer is 26.
Step-by-step explanation:
the total area = the area of full circle + the area of parallelogram = (π ×(8/2)²) + (28×7)
= (3,14 ×16)+(196)
= 50,24 +196
= 246,24
= 246,2
Answer:
#9: 1.2
#10: 1.25
Step-by-step explanation:
To find the scale factor of the smaller figure to the larger figure, we're going to be dividing the measurements of corresponding edges.
![\frac{larger figure}{smaller figure}](https://tex.z-dn.net/?f=%5Cfrac%7Blarger%20figure%7D%7Bsmaller%20figure%7D)
If you wanted to find the scale factor of the larger figure to the smaller figure, you'd do: ![\frac{smaller figure}{larger figure}](https://tex.z-dn.net/?f=%5Cfrac%7Bsmaller%20figure%7D%7Blarger%20figure%7D)
Question #9:
Left edges:
⇒
= 1.2
Bottom edges:
⇒
= 1.2
<em>(You should get the same number as long as the figures are similar.)</em>
<em />
Question #10:
Bottom edges:
⇒
= 1.25
<em>(There are no corresponding edges with measurements that we can compare.)</em>
<em />
~Hope this helps!~
Answer:
y = 18
Step-by-step explanation:
Since the triangles are similar, the corresponding sides are in proportion, that is
=
, substitute values
=
( cross- multiply )
14y = 252 ( divide both sides by 14 )
y = 18
