<span>a = 1/2 x b x h
h = 3b
so 1/2 x b x 3b = (1/2)(3b^2) = 150
(150 x 2)/3 = b^2
100 = b^2
b = square root of 100 = 10
h = 3b = 3 x 10 = 30</span>
If you want to multiply a decimal by a whole number, just ignore the decimal point and multiply like normal! Then, bring the decimal point back for the answer. for example 2×0.2
first multiply 2*2=4
and then place the decimal we have one value after decimal so the answer is 0.4
Answer:
The fourth one Its tell you to add or miners or multiple
Step-by-step explanation:
And then the rest is telling you to explain you answer using your own words.
Answer:
2m
Step-by-step explanation:
(m+3) (m-1)
We need to FOIL
first m*m = m^2
outer -1*m = -m
inner = 3m
last 3*-1 = -3
Add these together
m^2 -m +3m -3
m^2 +2m -3
I think that it is c or d but correct me if i am wrong
