I need help with this problem
Anarel [89]

The midpoint lines are half the opposite side length.

Line DE is given as 7 , So Line F = 7 x 2 = 14

Line EF is given as 12, so Line D = 12 x 2 = 24

Line DF is given as 16, so line E = 16 x 2 = 32


The perimeter is the sum of the 3 sides:

Perimeter = 14 + 24 + 32 = 70

Solve the following problem for the roots by using the quadratic formula. 2(6 - x) = x(x + 5)
stiv31 [10]
Solve for x:
2 (6 - x) = x (x + 5)
Expand out terms of the left hand side:
12 - 2 x = x (x + 5)
Expand out terms of the right hand side:
12 - 2 x = x^2 + 5 x
Subtract x^2 + 5 x from both sides:
-x^2 - 7 x + 12 = 0
Multiply both sides by -1:
x^2 + 7 x - 12 = 0
x = (-7 ± sqrt(7^2 - 4 (-12)))/2 = (-7 ± sqrt(49 + 48))/2 = (-7 ± sqrt(97))/2:
Answer:  x = (-7 + sqrt(97))/2 or x = (-7 - sqrt(97))/2

Logarithims pls help
NemiM [27]

The logarithm : log_{12} (7^{16} ) ÷ log_{12} (7^4) = 4.

  • Logarithm, the exponent or electricity to which a base should be raised to yield a given number.
  • Expressed mathematically, x is the logarithm of n to the bottom b if b^x = n, wherein case one writes x = log_b n.
  • Logarithms are described because the answers to exponential equations and so are nearly beneficial in any scenario in which one wishes to remedy such equations (together with locating how lengthy it's going to take for a populace to double or for a financial institution stability to attain a given fee with compound interest).
  • A logarithm is the electricity to which a number of should be raised so that it will get a few different number.
  • For example, the bottom ten logarithm of a hundred is 2, due to the fact ten raised to the electricity of is a hundred: log(100) = 2.
