Answer:1375
Step-by-step explanation:
X= 15 is given
X squared is 15x15 = 225
1600 - 225= 1375
Vertex coordinates: (h, k)
Vertex form: y = a(x-h)^2 + k
y = 2(x+3) + 2(x+4)
Use distributive property:
y = 2((x+3)+(x+4))
Simplify:
y = 2(2x+7)
y = 4x+14
This is slope - intercept form, not vertex form. Vertex form is for quadratic equations - this is a linear equation.
Answer (in slope - intercept form):
y = 4x+14
Slope = (2+5)/(-3-1) = 7/-4 = -7/4
answer is B -7/4
Answer:
30
Step-by-step explanation:
5*2*3-2*0 ( when we multiply any number with zero then the result is also zero)
30-0

Answer:
5.7
Step-by-step explanation:
pythagorean theorem
A^2 + B^2 = C^2
sub in
A^2 + 7^2 = 9^2
simplify
A^2 + 49 = 81
solve
A^2 = 32
solve further
A = 
use calculator and get:
