Given:
3x(x - 2) + 2 and 2x² + 3x -12
If x = 7 then,
= 3(7)(7 - 2) + 2
= 21(5) + 2
= 107
= 2(7)² + 3(7) -12
= 2(49) + 21 -12
= 98 + 9
= 107
<em>For x = 7, each expression has a value of 107.</em>
<em />
If x = 2 then,
= 3(2)(2 - 2) + 2
= 6(0) + 2
= 2
= 2(2)² + 3(2) -12
= 2(4) + 6 -12
= 8 - 6
= 2
<em>For x = 2, each expression has a value of 2.</em>
<em>These results suggests that the expressions are equivalent, but (I don't know the choices) the expressions are equivalent. </em>
Answer:
a. 15cm
b. 36ft
c. 35in
d. 44mm
e. 13km
f. 25ft
Step-by-step explanation:
a. 4cm + 6cm + 5cm = 15cm
b. 9ft + 9ft + 9ft + 9ft = 36ft
c. 5in + 7in + 7in + 8in + 8in = 35in
d. 12mm + 12mm + 10mm + 10mm = 44mm
e. 4km + 3km + 4km + 2km = 13km
f. 6ft + 3ft + 4ft + 4ft + 8ft = 25ft
Answer:
23
Step-by-step explanation:
19346 ÷ 841 = 23.003567.. ( that is 23 with a remainder ), then
23 × 841 = 19343, thus
19346 ÷ 841 = 23 remainder 3
The divisor is 23
