Answer: C. 20 inches
Step-by-step explanation:
perimeter= 2 x (4+6)=20 inches
Answer:
It would be -4
Step-by-step explanation:
a double negative becomes a + sign
So, -10 + 6=-4
(10+2x)(8+2x) = 120
4x^2 + 36x + 80 = 120
x^2 + 9x + 20 = 30
x^2 + 9x - 10 = 0
(x+10)(x-1) = 0
x = 1 inch dimension
Answer:
gradient = 2
Step-by-step explanation:
Calculate the gradient (slope) m using the slope formula
m =
with (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (6, 10) ← 2 points on the line
m = = = 2
