Answer:

m^2-4m-45=0

Step-by-step explanation:

There are many more answers to this question, but if we're asking for some kind of <em>polynomial </em>equation, any polynomial with two solutions is of degree two. If m=-5, we can also say that m+5=0, and if m=9, then m-9=0. We can combine these two statements by saying that (m+5)(m-9)=0 when either m=-5 or m=9. Expanding that equation out, we get the expanded form m^2-4m-45=0

Answer:

\frac{21}{4}

Step-by-step explanation:

Given

3 × \frac{7}{4} ← can be expressed as

\frac{3}{1} × \frac{7}{4}

Multiply numerators/ denominators, that is

Kindly answer this one. Thank you.​
steposvetlana [31]

Answer:

See below.

Step-by-step explanation:

I'm assuming these questions are about the Midline Theorem (segment AL joins the midpoints of the non-parallel sides.

♦  The midline's length is the average of the lengths of the top and bottom parallel sides.

AL=\frac{OR+CE}{2}

Use this equation and substitute values given in each problem, then solve for the missing information.

1. AL = x, CE = 9, OR = 5

x=\frac{9+5}{2}=7

2. AL = <em>m</em> - 4, CE = 15, OR = 17

m-4=\frac{15+17}{2}=16\\\\m-4=16\\\\\\m=20\\\\AL=20-4=16

3. OR = y + 5, AL = 15, CE = 18

15=\frac{(y+5)+18}{2}\\\\15=\frac{y+23}{2}\\\\30=y+23\\\\7=y\\\\OR = 7+5=12

dalvyx [7]

Answer:

Paul earned $2.6 more interest than Monica.

Step-by-step explanation:

Giving the following information:

Monica:

Initial investment= $300

Interest rate= 4.2%

Paul:

Initial investment= $400

Interest rate= 3.8%

<u>To calculate the income earned, we need to use the following formula:</u>

I= P*r*t

P= principal

r= interest rate

t= time

Monica:

I= 300*0.042*1= $12.6

Paul:

I= 400*0.038*1= $15.2

Paul earned $2.6 more interest than Monica.
