Lin has 4 pinecones and some acorns.

frozen [14]

Answer:

Lin has 11 acorns ⇒ answer D

He subtract 4 from 7 instead of add 4 to 7

Step-by-step explanation:

- Lin has 4 pinecones and some acorns

- She has 7 fewer pinecones than acorns

- The meaning of 7 fewer pinecones than acorns is the number of the

pinecones is less than the number of acorns by 7

∵ She has 4 pinecones

∵ She has 7 fewer pinecones than acorns

- The number of pine cones is less than the number of acorns by 7

∴ 4 = number of acorns - 7

- Add 7 to both sides

∴ 11 = number of acorns

* Lin has 11 acorns

- Tom choose answer A which is 3

- He made a mistake in the equation

- He put ⇒ number of the acorns = 7 - 4 not 7 + 4

∴ number of acorns = 3

* He subtract 4 from 7 instead of add 4 to 7

Which set of side lengths is a Pythagorean triple? 1,3,10 4,5,9 9, 40, 41 16, 30, 44

Elina [12.6K]

Answer:

Which set of side lengths is a Pythagorean triple? 9, 40, 41

Step-by-step explanation:

$c = \sqrt{ {a}^{2} + {b}^{2} }$

9 = a

40 = b

41 = c

$c = \sqrt{ {a}^{2} + {b}^{2} } \\ c = \sqrt{ {9}^{2} + {40}^{2} } \\ c = \sqrt{81 + 1.600} \\ c = \sqrt{1.681} \\ c = 41$

Consider the quadratic equation x squared = 4x - 5. how many solutions does the equation have?

snow_lady [41]

Answer:

The quadratic equation has two complex solutions

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}=4x-5$

Equate to cero

$x^{2}-4x+5=0$

$a=1\\b=-4\\c=5$

substitute in the formula

$x=\frac{4(+/-)\sqrt{-4^{2}-4(1)(5)}} {2(1)}$

$x=\frac{4(+/-)\sqrt{16-20}} {2}$

$x=\frac{4(+/-)\sqrt{-4}} {2}$

Remember that

$i^{2}=-1$

$x=\frac{4(+/-)2i} {2}$

$x=2(+/-)i$

therefore

The quadratic equation has two complex solutions
