How to solve for x 8(4-x)= 7x+2

Answers

Answer 1
Answer: 8 ( 4 - x ) = 7x + 2
32 - 8x = 7x + 2
      -7x     -7x
--------------------------
32 - 15x = 2
-32           -32
----------------------------
-15x = -30
/-15      /-15

x = 2.

What is the area of the triangle when a=14 and c=50 what is b?

Answers


No answer is possible.
Without the picture ... or a detailed explanation ...
it's not possible to tell what 'b' is.
B is 116. The area of any triangle should equal 180. So you add 14 plus 50 to get 64 and then you subtract 180 minus 64 and get 116. Got it?

In between given 6 exponential expressions, ((36)/(4) )^(x), 9 × 9^(x - 1), and  (36^(x))/(4^(x)) are equivalent to 9^(x)

What is an exponential expression?

"An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable."

Given expression is 9^(x).

a. 9 × 9^(x + 1) is equal to  9^(x + 2).

b. ((36)/(4) )^(x) is equal to 9^(x).

c. (36^(x))/(4) is equal to 9^(x) × 4^(x - 1).

d. 9 × 9^(x - 1) is equal to  9^(x).

e. (36^(x))/(4^(x)) is equal to  9^(x).

f. x^(5) is equal to x^(5) .

Therefore, from the given expressions,  ((36)/(4) )^(x), 9 × 9^(x - 1), and  (36^(x))/(4^(x)) are equivalent to 9^(x).
