Answer:
x = -8
Step-by-step explanation:
Given: 5(x+4)+52=-4x
Distributive Property: 5x+20+52=-4x
Combine like terms: 5x+72=-4x
Subtract 5x on both sides: 72=-9x
Divide both sides by -9: -8=x
Flip the equation around: x=-8
Therefore, x=-8

Answer:
A. 2^11
Step-by-step explanation:
(They are basically asking what's 2^4 × 2^7, but with more words.)
I usually do each exponent individually:
2^4 is the same as 2 × 2 × 2 × 2 = 16 (or you could have read the text to figure that out)
2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 = 128
Then just multiply 128 and 16 to get 2,048, and see which option also gives you 2,048.
BUT, you can also:
(Combine the exponents together to get your answer. Just remember that if it's multiplication you add them, and if it's division you subtract them.)
2^4 × 2^7
4 + 7 = 11
2^11 (This equals 2,048 btw. You don't even have to check all the options to get the answer).
Hope this helps friend :)
The last part I learned from another user, while answering one of your other questions. I personally find this mind blowing, lol.
10⁻⁵ is the same number as 1 / 10⁵ .
