Step-by-step explanation:
To tell if JKON and JKLM are similar, compare the ratios between corresponding sides. For example:
JK / KO = 5/8
JK / KL = 5/22
The ratios aren't the same, so the shapes aren't similar.
Answer:
Solution given:
the angles 2xº and 4yºare complementary
so
2x+4y=90°
dividing both side by 2we get
x+2y=45°
<u>the value of x + 2y</u><u> </u><u>i</u><u>s</u><u> </u><u>4</u><u>5</u><u>°</u><u>.</u>
150
13+46= 59
59+87= 146
Round 46 to the nearest ten, which in this case would be 50 because the last number is larger than a 5.
Then add the 1 back in to make it 150.

Distribute:
=−x2+−4x+−4+7
Combine Like Terms:
=−x2+−4x+−4+7
=(−x2)+(−4x)+(−4+7)
=−x2+−4x+3
Answer:
=−x2−4x+3
Answer:
C
Step-by-step explanation:
Triangle CGF and triangle CED are similar. Hence, the ratio of their corresponding sides are equal. Thus we can write:
<em>We can now cross multiply and solve for CD:</em>
Since GF is a midsegment of CDE, CD is double of CF. So we can write:
<em>By using quadratic formula 
and with a=3, b= -5.2, and c= -1.6, we find the value of x to be:</em>
<em>Since the expression for CD is 
, we plug in 
into this expression to find value of CD:</em>
The correct answer is C
