(x+7)(x+9) <br>Do this math problem by using the Foil method.

Setler79 [48]

Foil:
First term
Outer term
Inner term
Last term

By using foil we just times the first terms together so: x*x=x^2

Then we times the outer terms together so: x*9=9x

Then we times the inner terms together so:7*x=7x

Finally we times the last terms together so: 7*9=63

So our equation is:
X^2+9x+7x+63

Now we collect the like terms

Answer: x^2+16x+63

Hope this helped

A high interest savings account pays 5.5% interest compounded annually. If $300 is deposited initially and again at the first of

Ann [662]

Answer:

$ 4075.05

Step-by-step explanation:

Given :

R = Interest rate = 5.5%

T = Duration of Payment = 10 years

FV = Future Value

A = Amount

The amount of deposited in the account for 10 years from the date of initial deposit is $300

We are given that the Interest rate in the account is 5.5%

So by formula :

$FV = A(\frac{(1+r)^{t}-1}{r}).(1+r)$

$FV = 300(\frac{(1+.055)^{10}-1}{.055}).(1+ .055)$

$FV = 300(\frac{(1.055)^{10}-1}{.055}).(1.055)$

$FV = 300(\frac{1.708144458-1}{.055}).(1.055)$

$FV = 300(\frac{0.708144458}{.055}).(1.055)$

$FV = 300\times 12.875353782\times 1.055$

$FV = 4075.05$

Thus , Total summation of money in the account after 10 years is given by the following equation =$ 4075.05

Total money in account after 10 years is $ 4075.05

A same side interior angle of two parallel lines is three times the other same side interior angle. Find the measures of these t

vredina [299]

Answer:

45 , 135

Step-by-step explanation:

As we know the property of interior angle if there are two parallel lines i.e The sum of two angle is 180.

Let the First angle be x then other angle 3x

So

x + 3x= 180 [ By the interior property the sum of two angle is 180]

4x=180

$x=\ \frac{180}{4} \\x=45$

Therefore Other angle is 3*45= 135
