If f (x) =- 4x2 +15, then f (-3) = -21
Answer:
2
Step-by-step explanation:
With regards to the above, we can sum up the foods ate together by the 5 cats, then we have;
= 1/5 + 1/5
= 2/5
Then we can multiply the value above by the 5 cats
= 2/5 × 5
= 10/5
= 2
The cats eat 2 foods together.
Answer:
273 m^2
Step-by-step explanation:
Firstly, you should find the area of the triangle. Remember that the formula for a triangle's area is (Base x Height) ÷ 2
Therefore,
11 x 14 is 154
154/2 = 77 m^2
Then, we find the area of the square which is just Base x Heigh
14 x 14 is 196m^2
And finally, we just add the two
77 + 196 = 273 m^2
The reason it's not m^3 is because we're not dealing with a third dimensional figure.
Btw, ^ means to the power of.
