Answer:
Step-by-step explanation:
It is (3,-1).
16 bc all sides of a square are congruent and area = LxW so 4x4=16
Answer:
x = -5
x = -12
Step-by-step explanation:
- 7x - 60 = x^2 + 10x
add 7x to both sides
x^2 + 17x = -60
add 60 to both sides
x^2 + 17x + 60 = 0
factorise quadratic
(x + 12) (x + 5) = 0
<em>x = -12</em>
<em>x = -12x = -5</em>
Answer:
13
Step-by-step explanation:
It is just the multiplication of vectors. We'll multiply corresponding pairs together. The general formula for the pairs of (
;
) and (
;
) is
