The product of two integers is 112. One number is four more than three times the other. Which of the following equations could b

shepuryov [24]

Answer:

The equations could be used to find one of the numbers is, $3a^2 + 4a =112$

Step-by-step explanation

Let two integers be a and b.

As per the given statement:

The product of two integers is 112.

⇒ $ab =112$ ......[1]

Also, One number is 4 more than three times the other.

⇒b = 3a +4 ......[2]

Now substitute equation [1] in [2] we get

$a(3a+4) =112$

Using distributive property i.e, $a \cdot (b+c) = a\cdot b + a\cdot c$

$(a)(3a)+ 4a = 112$

Simplify:

$3a^2 + 4a =112$

therefore, the equation that could be used to find one of the numbers is;

$3a^2 + 4a =112$

How many solutions does -(9x+12)=-8x-(x+3) have

Viktor [21]

-(9x+12)=-8x-(x+3)
-9x-12= -8x-x-3
-9x+9x=9
-9

if u look at the eq for x it has no value. but if u r asking a solution for a eq then it is -9

Check out attachment:) I don't understand how do you find out the length ?? pls help with explanation thx

Answer:

x=3.89

Step-by-step explanation:

I'll go in depth for you.

Before we figure out what we do, let understand what we know about this triangle.

We know that both triangles have a angle that measure 27°.
We also know EH=5
FG=9
ZG=7
We need to know how to find EZ

Notice how line EG and HF intersect at Angle Z. We know that if two lines intersect at an angle, it form angles called vertical angles. This means that the two angles that are vertical to each other are congruent.

This means that angle Z in both triangles both measure the same.

Now since both triangles have 2 congruent corresponding angles, we can say that the Triangles are Similar due to the Angle-Angle Postulate.

"If two corresponding angles of two triangles are congruent, then the two triangles are similar."

What is mean when Triangles are similar? 

It means that the similar triangles corresponding angles are equal and their sides are in proportion.

The corresponding sides are 

EH and GF

EZ and ZG

HZ and HF.

Our proportion formula for similar triangles is 

Any two sides of the first triangle divided by each other must equal the two corresponding sides of the second triangles divided by each other respectively.
