Can someone help me with the top 1-3. Using similar figures subject

Mathematics

Answer: <M corresponds to <J
               <L corresponds to <O
               JL corresponds to MO 

To find the corresponding angles:
1. Look at the figures. 
<M is to <J, <N is to <K, and <O is to <L.

2. Look at the similarity statement. 
ΔMNO ~ ΔJKL. <M is to <J because they are the first letters.
ΔMNO ~ ΔJKL. <N is to <K because they are second letters.
ΔMNO ~ ΔJKL. <O is to <L because they are third letters.

Apply these two methods to find the corresponding sides.

Factoring Trinomials
alexandr402 [8]
25 a² + 20 ab +  4 b²

for formula a^x+bx^ky^k+cy ^{2k } find  u,v such that: u.v = a

and u+v = b  then  group according to (ax ^{2k} +ux^ky^k)+(vx^ky^k+cy ^{2k} )

= (25a^2+10ab)+(10ab+4b^2)

factor out 5a from : 25a^2+10ab : 5a(2b+5a)

factor out 2b from : 10ab+4b^2: 2b(2b+5a)

= 5a(2b+5a) + 2b(2b+5a)

factor out : (5a+2b)

= (5a+2b)(5a+2b)

Refine:

(2b+5a)^2

hope this helps!.

Hello there!

|a - b| - |c + d|

|-5 - 4| - |1 +(-3)|

=|-5 - 4| - |1 - 3|

= |-9| - |-2|

Solve for the absolute value

= 9 - 2

= 7

If two angles are both vertical and supplementary, can we determine the angles? Is it possible to be both vertical and complemen
Lorico [155]

Answer:

i. Two angles can be vertical and supplementary.

ii. Yes, we can determine the angles.

Step-by-step explanation:

When two angles are vertical, it implies that they are equal (with respect to vertical opposite property). While two angles are supplementary if and only if they add up to 180 degrees .

It is not mandatory for the two angles to be beside each other so as to be supplementary. So that in this special case, the only measure of angles that can be both vertical and supplementary is 90 degrees .

This answer is right. Please mark Brainliest!

G(x) = -3x² – 2<br> f(x) = -4x-1<br> Find f (4) and g(6).
KiRa [710]

Answer:

f(4)= -17

g(6)= -110

Step-by-step explanation:

g(x)= -3x^2 -2

g(6)= -3*6^2 - 2

      = -108 -2

       =-110

f(x) = -4x-1

f(4) = -4*4 -1

     =-17
