The answer is 290 inches squared.
The surface area is = the sum of all sides. There are 4 sides that equal 60 (60 x 4 = 240), and 2 sides that equal 25 (25 x 2 = 50), the surface area is equal to 240 + 50 which equals 290.

Answer:

290 in^2

Step-by-step explanation:

So what you do is you use the formula of the surface area of a rectangle which is SA=2lw+2lh+2hw.

The length=5. The width=5. The height=12.

You put those numbers into the formula.

2(5)(5)+2(5)(12)+2(12)(5)=290 in^2.

Solve 6^x+2 = 10 for x using the change of base formula
pashok25 [27]

Answer:

x\approx-0.7149

Step-by-step explanation:

\displaystyle 6^{x+2}=10\\\\\log_6(6^{x+2})=\log_6(10)\\\\x+2=\frac{\log(10)}{\log(6)}\\\\x+2\approx1.2851\\\\x\approx-0.7149

Recall that the change of base formula is \displaystyle \log_a(b)=\frac{\log(b)}{\log(a)}

Evaluate for x=4 and y=-3 write in simplest form<br> 2y/x2
lorasvet [3.4K]

Hello from MrBillDoesMath!

Answer:

I think your formula  (2y/x2) is equivalent to

(2*y)/(x^2)      where x^2 means x-squared.

If so, then

(2*y)/(x^2) = (2*3)/(4*4) = 6/16 = 3/8

Thank you,

MrB

the length of a rectangular garden is 3 m greater than the width. The area of the garden is 70m squared. find the dimensions of
Lerok [7]
A = l x w

so you know that the length is 3m longer than the width, so you could use a formula to represent that

w = l + 3

you then substitute the second equation into the first to solve for l

70 = l x (l +3)
70 = l^2 + 3l

you could then rearrange the formula and solve for l using the quadratic formula 

0 = l^2 + 3l - 70

l = -3 +- (square root (3)^2 - 4(1)(70)) / 2(1)
l = -3 +- (square root 9 + 280) / 2
l = -3 +- (square root 289) / 2
l = -3 +- 17 / 2

then you solve for the two seperate roots

l = -3 + 17 /2
l = 14 / 2
l = 7

or 

l = -3 - 17 / 2
l = -20 / 2
l = -10

since a length cannot be negative, this root is not viable. therefore l = 7

to solve for w you would use

w = l + 3
w = 7 + 3
w = 10 

hope this helps! if you did not understand a step or concept please let me know!
