Answer:
14
Step-by-step explanation:
44-9=35
35+77=122
122÷8=14
Answer:
x^2+2x+3 I sent the answer
Length of the outer frame: 4+2x
width of the outer frame: 3+2x
area of the outframe: (4+2x)(3+2x)=15
expand the equation: 12+8x+6x+12x^2=15
combine like terms: 4x^2+14x-3=0
Sum of interior angles in a triangle = 180
So <A + <B + <C = 180
<A = 180 - <B - <C
<A = 180 - 43 - 15
<A = 122
Answer
<A = 122°
Answer:
-3(z-x) = y
Step-by-step explanation:
Z=x-y/3
Solve for y
Subtract x from each side
z-x = x- y/3 -x
z-x = -y/3
Multiply each side by -3
-3(z-x) = -y/3 * -3
-3(z-x) = y
