Question

a) If Δ+145=−115 ,then Δ= ? (Consider Δ as variable) b) 3(∅+ 4)−2=4, then ∅=?

Answer 1

Step-by-step explanation:

6-the extremities

triangle

of the

of the base of an isosceles

are the points (2a,0) and 10, a) and

of the sides is x=2a

the equation of one of

then

of the triangle

square

(A) 5/ a al

(3) 5/pa

units is :

(c) 250

4) sa

4

Answer 2

Answer:

a) ∆ + 145 = -115

∆ = -115-145

∆ = -260

b) 3(∅ + 4) -2 = 4

3∅ +12-2 = 4

3∅ +10 = 4

3∅ = 4 - 10

3∅ = -6

∅ = -6/3

∅ = -2
