Answer : x^7

When you’re multiplying variables like the one in the problem above, instead of actually multiplying, you add. You only multiply in cases where there are coefficients.

Example : z^4 * z^2

Instead of multiplying, you would add the exponents together like so, z^6.

steposvetlana [31]

Answer:

The amount is $1480.24

Step-by-step explanation:

We are given

he puts $1000 in a savings account earning 4% annually after 10 years

so,

P=1000

r=4%=0.04

t=10

now, we can use formula

$A=P(1+r)^t$

now, we can plug values

$A=1000(1+0.04)^{10}$

$A=1480.24428$

So,

The amount is $1480.24

What is the value of x? Enter your answer in the box. x= __

RoseWind [281]

Answer:

x =20

Step-by-step explanation:

We can use similar triangles and proportions to solve. Take the smaller triangle side on top and the larger triangle side on the bottom.

11 10

---------- = --------------

11+121 10 +5x+10

Combine like terms

11 10

---------- = --------------

132 5x+20

Using cross products

11*(5x+20) = 10*132

55x+220 = 1320

Subtract 220 from each side

55x+220-220 = 1320-220

55x = 1100

Divide by 55

55x/55= 1100/55

x =20
