6x - 2 = 46, by law of alternate-interior angles (when a transversal intersects 2 parallel lines).
6x -2 +2 = 46 +2
6x = 48
6x/6 =48/6
x = 8

The answer is 22 because the sum of the angles is equal to 180 and so the missing angle next to the 46 is 134. If you subtract 2 from 134 and divide 132 by 6 it gives you 22. Therefore the answer is 22.

What is X squared +3x-70

Aleksandr-060686 [28]

Answer:

x = 7, x = -10

Step-by-step explanation:

$x^2+3x-70 = 0$

Use the quadratic formula.

$x = \frac{-3 + \sqrt{3^2-4(1)(-70)} }{2(1)} \\x = \frac{-3 - \sqrt{3^2-4(1)(-70)} }{2(1)} \\$

Solve.

x = 7, x = -10

You can also factor if you want - that is a faster method.

Expand
$\lim_{h \to 0} \frac{5(x^2+2hx+h^2)-2)-5x^2+2}{h}$

$\lim_{h \to 0} \frac{5x^2+10hx+5h^2-2-5x^2+2}{h}$

$\lim_{h \to 0} \frac{10hx+5h^2}{h}$

$\lim_{h \to 0} 10x+5h$
say h=0 so

If the probability that a bird will lay an egg is 75%, the probability that the egg will hatch is 50%, and the probability that

garik1379 [7]

Answer: (A) 30%

Step-by-step explanation:

Given : The probability that a bird will lay an egg =0.75

The probability that the egg will hatch =0.50

Now, the probability that the egg will lay an egg and hatch = $0.75\times0.50$

Also,The probability that the chick will be eaten by a snake before it fledges =0.20

Then, the probability that the chick will not be eaten by a snake before it fledges : 1-0.20=0.80

Now, the probability that a parent will have progeny that survive to adulthood will be :-

$0.75\times0.50\times0.80=0.30=30\%$

Hence, the probability that a parent will have progeny that survive to adulthood = 30%
