Answer:
1 Chair= $1.25 1 table= $8.25
Step-by-step explanation:
5c+3t=31
2c+6t= 52
-2(5c+3t=31)
-10c-6t=-62
+
2c+6t=52
= -8c=-10
/-8 /-8
c= 1.25 or 1 1/4
2c+6t=52
2(1.25)+6t=52
2.5+6t=52
-2.5 -2.5
6t= 49.5
/6 /6
t= 8 1/4
Answer:
Greatest Common Factor: integer or variable multiplied by other integers or variables that creat a resultin product. factor x factor = product
difference of squares binomial: an expression where two perfect square terms are being subtracteda² - b² = (a+b)(a-b)quadratic: from "quad" meaning square, because the variable gets squared (like x2).
discriminant: tells you about the roots of a quadratic
general form: y = a(x - h)^2 + kstandard form: ax^2 + bx + c = 0root: a solution of an equation
zero: a value that gives you 0 for a function
x-intercept: where the graph crosses the x-axis
y-intercept: where the graph crosses the y-axis
extraneous: a solution that does not work
parabola: the graph of a quadratic
vertex: the turning point of the parabola
axis: line of reflection
translation: movement up/down and left/right of any parabola from standard position (f(x) = x2)

Can get brainiest pls
Answer:
420m²
Step-by-step explanation:
Given that:
Length of diagonal = 42m
Lenght of outlying vertice = 10 m
Area of paralellogram = 2 " (area of triangle)
Area of triangle = 1/2 * base * height
Hence,
Area of parallelogram :
Area = 2(0.5 * 42 * 10)
Area = 2 (210)
Area = 420m²
The triangle BCD is an acute triangle
