Mr Green: $4(3a+1+2b) = 12a + 4 + 8b$

Mrs Green: $6(5a-a)+4(2+4b)=6*4a + 8 + 16b = 24a +16b + 8$

Keith: $4(2+4b+6a) = 8 + 16b + 24a=24a+16b + 8$

Kevin: $4(6a+2)+8b + 2 = 24a + 8 + 8b + 2 = 24a + 8b + 10$

Thus Mrs Green and Keith has the expression that is equivalent to

'24a + 16b + 8'

Hope that helps!

Explain the difference between accuracy and precision

nata0808 [166]

Precision is more like consistency. Take a rifle range for example. Sure, all the shots may be off centered, but if they're tightly grouped together, it shows that the shooter had precision in their shooting. Accuracy is how close to spot on the attempts or shots generally are. They would end up more towards the center, but a little more spread out.

What are the values of sin α and tan α, if:<br> cosα=0.6

olganol [36]

Positive cosine is first or fourth quadrant. So we don't know the sign of the sine or the tangent.
