1. m/n=5, m= 5n,  
(5n)²-25n²=25n²-25n²=0

2.3/x=5/y
3y=5x
y/x=5/3

3. (3x+5)²=9x²+2*3x*5+5²= 9x²+30x+25
y=ax²+bx+c, so a=9,b=30,c=25,   a+b+c=9+30+25= 64

4.how I understand,   it should be solved the equation
8^(2x-1)=4^(3x+4)

(2^3)^(2x-1) = (2^2)^(3x+4)
2^(3*(2x-1))=2^(2*(3x+4))
3*(2x-1)= 2*(3x+4)
6x-3=6x+8
-3=8 false,
so this equation has NO solutions
(if the equation was written correctly)

In triangles DEF and OPQ, ∠D ≅ ∠O, ∠F ≅ ∠Q, and segment DF ≅ segment OQ. Is this information sufficient to prove triangles DEF a
kenny6666 [7]

In triangles DEF and OPQ, ∠D ≅ ∠O, ∠F ≅ ∠Q, and segment DF ≅ segment OQ; this is not sufficient to prove triangles DEF and OPQ congruent through SAS

<h3>What are congruent triangles?</h3>

Two triangles are said to be congruent if they have the same shape, all their corresponding angles as well as sides must also be congruent to each other.

Two triangles are congruent using the side - angle - side congruency if two sides and an included angle of one triangle is congruent to that of another triangle.

Please help me get this right I don’t know how to do it.
velikii [3]

Answer:

tan∠E=1/3

Step-by-step explanation:

Tangent or opposite/adjacent of angle E is segment HF/3 to solve for HF you can use sine of H opposite over hypotenuse or √8/HF=sin45°. Rearranging the equation you get √8/sin45°=HF and sin45°= 2√2 so √8/2√2=1 HF=1 now you know that tan(∠E)=1/3.

Find −315÷134. Write your answer as a mixed number in simplest form.
kipiarov [429]

Answer:

-2\frac{47}{134}

Step-by-step explanation:

-2\frac{47}{134} = -\frac{315}{134}

134can go into -315twice at the most, so doubling 134will give us 268, which leaves us with 47left over to reach 315, which is why 47is the numerator. The remainder is ALWAYS the numerator.

I am joyous to assist you anytime.
