Find the perimeter & area of the rectangle. 2x-3 5(x-2)

Mathematics
1 answer:
shtirl [24]3 years ago
4 0

Step-by-step explanation:

The perimeter of a rectange is :

P = 2(L+B)

L is length and B is breadth

L = 2x-3 and B = 5(x-2)

⇒P = 2(L+B)

P = 2[2x-3+5(x-2)]

P = 2[2x-3+5x-10]

P = 2[7x-13]

The area of a rectangle is :

A = L×B

A=(2x-3)\times 5(x-2)\\\\A=(2x-3)\times(5x-10)\\\\A=10x^2-10x-15x+30\\\\A=10x^2-25x+30

You invested $10,000 into two accounts: one that has a simple 3% interest, the other with 2.5% interest. If your total interest
artcher [175]

Answer:

3300 was on 3% and 6700 on 2,5%

Step-by-step explanation:

We can say that 'a' represents the price that will go on 3% interest and 'b' 2,5% interest.

Therefore;

a + b = 10 000

And

0,03a + 0,025b = 283.5 (0,03 means 3% etc)

You can move 'b' to the other side to leave 'a' on the LHS

0,03a = 283.5 - 0,025b - - > (divide both sides by 0,03)

a=9450 - 0,8333b

Substitute this equation as 'a' in the first equation to get:

9450 - 0,8333b + b = 10 000 (move 9450 to the RHS to leave values with b on the LHS)

-0,8333b + b = 10 000 - 9450

0,1666b = 550 (divide both sides by 0,1666)

b = 3,300

Therefore 'a' will be :

a= 10 000 - 3 300

a = 6700

I hope this helps.

Answer:

A

Step-by-step explanation:

We can substract the wavength of the violet light to the wavelength of the red light:

(6.5 x 10^-7 m) - (4.0 x 10^-7 m) = 2.5 x 10^-7 m

What’s the correct answer for this question?
xxMikexx [17]

Answer:

12.22

Step-by-step explanation:

To find HI, you have to use tangent. tanx=\frac{opposite}{adjacent}

tan(42°)=\frac{11}{HI} , then you multiply HI to both sides of equation and divide tan(42).

To get <em>HI</em>=\frac{11}{tan(42)}

Which makes HI equal 12.2167
