Step-by-step explanation:
→ Option A
x² - 11x + 28
= (x - 7)(x - 4) ❎
→ Option B
x² - 6x + 8
= (x - 4)(x - 2) ❎
→ Option C
x² + 7x + 12
= <u>(x + 4)</u>(x + 3) ✔️
The equation of a line which has the slope m and passes through the point A(x1,y1) has the formula:
y-y1=m(x-x1)
in your case m= -5 ; A(x1;y1)=(1;-1)
y-(-1)= -5(x-1)
y+1= -5(x-1)
answer is c
Answer:
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
Step-by-step explanation:
Rs 720
Cost of 1 m of cloth = 450/5= Rs 90
Cost of 8 m of cloth= 90*80= Rs 720
The volume is 70/9 or 7 7/9.
