Answer:

tge area of triangle is 36 in2 so she can only create 4 triangle

Step-by-step explanation:

area of square grid = 12 × 12

=144

area of triangle = 1/2 × 6 × 6

;;; = 18 ×2

=36

area if square grid/ area of triangle

=144/ 36

=4

Law of cosines: a2 = b2 + c2 – 2bccos(A) What is the measure of N to the nearest whole degree? 35° 45° 55° 65°
oksano4ka [1.4K]

Answer:

The measure of angle N is 55°

Step-by-step explanation:

we know that

the law of cosines established

a² = b² + c² – 2*b*c*cos(A)

so

In this problem we have

a=ML=5.74 units

b=LN=4 units

c=MN=7 units

∠A=∠N=?

see the attached figure to better understand the problem

a² = b² + c² – 2*b*c*cos(A)------> cos (A)=[b²+c²-a²]/[2*b*c]

cos (A)=[4²+7²-5.74²]/[2*4*7]------> 0.57236

A=arc cos (0.57236)--------> A= 55°

therefore

The measure of angle N is 55°

Answer:

a) 4x - 8y

b) 4 × x - 8 × y

c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication

Step-by-step explanation:

a) start with the parentheses

1/3 (6x - 12y)

multiply 6x and -12y by (1/3)

2x - 4y

so now the equation is 5x -3x -4y + 2x -4y

add together the like terms

5x -3x + 2x = 4x

-4y -4y = -8y

so we have 4x - 8y

b) im not good with factored form but i believe this is right

take 4x and separate them by turning it into 4 × x and same for -8y turn it into -8 × y

c) 4x - 8y is the same as 4 × x - 8 × y because if there is no simbol then it is always multiplication

im not sure how to prove them equal to the original expression i dont really remember that but i hope this helped
