C. It's understood that's there's a one in front of the sq rt of 2
So 3 sq rt of 2- 1 sq rt of 2 gives you 2 sq rt of 2
+2+(-3)+(-1)+4(-5)+(-3) ok so first 2 is positive and 3 is negative there both different signs so u subtract +2+(-3)=-1+(-1)=0+4=4+(-5)=-1+(-3)=-4 your answer is 4
Answer:
10cm
Step-by-step explanation:
the formula for an area of a trapezium:
where a and b are the parallel sides and h is the height. equating what we have:
simplify the numerator by adding 19.8 and 7.2=27
multiply both sides by 2
divide both sides by 27
the height is 10cm
Answer:
D. y = –3x2
Step-by-step explanation:
Answer:
y = -3x^2
Step-by-step explanation:
A quadratic function has a leading coefficient which determines its width. When |a| < 1 the graph is wider. When |a| > 1 the graph is narrower. This means y = -3x^2 is the narrowest graph since 3 is the greatest.
