1)
4m-4=4m
4m+4m=4
8m=4
m=0.5
2)
y°=kx°
Find k.
4=k/(2/3)
k=8/3
Find x¹.
y¹=kx¹
18=(8/3)×x¹
18x¹=54
x¹=6 3/4
Megan would need to use 6 3/4 cups of almond.
Answer:
(x+1) (7x - 4)
Step-by-step explanation:
7x² + 3x - 4
Use the diamond...
7 times -4 equals -28 and 7 plus -4 = 3
Use factor by grouping b/c a does not equal 1
7x² + 7x - 4x - 4
7x(x + 1) -4(x + 1)
(x+1) (7x - 4)

Taking the side we can't quite see, I would guess it is an 8.
A 45 45 90 triangle is isosceles.
The two legs are equal.
x = 8

Little harder
The tangent of the angle is Tan(x) = opposite over adjacent
opposite = 10
adjacent = 15
Tan(x) = 10/15
Tan(x) = 2/3
x = tan-1(2/3)
x = tan-1(0.6666666667)
x = 33.7 degrees.
Do you know how to put this in your calculator.
