with a line
Step-by-step explanation:
so you get a use a graph calculator and you put in that and it shows the answer.
Answer:
Option C and E are correct.
Step-by-step explanation:
We need to solve the following equation
(2x+3)^2=10
taking square root on both sides
Now solving:
So, Option C and E are correct.

Answer:
AC = 8 cm,
AD = 3 cm and ∠ACB = ∠CDA
From figure,
∠CDA = 90°
∴ ∠ACB = ∠CDA = 90°
In right angled ∆ADC,
AC2 = AD2 + CD2
⇒ (8)2 = (3)2 + (CD)2
CD2 = 64 – 9 = 55
⇒ CD = √55 cm
In ∆CDB and ADC.
∠BDC = ∠AD [each 90°]
∠DBC = ∠DCA [each equal to 90°-∠A]
∴ ∠CDB ∼ ∆ADC
Then,
The answer is C
if you put x and y in each equation it becomes true
