Answer:
to estimate the result of multiplication (product), round the numbers to some close numbers that you can easily multiply mentally. One method of estimation is to round all factors to the biggest digit (place value) they have.
Step-by-step explanation:
Answer:
Scalene
Step-by-step explanation:
With this question, it's best to draw it out or we can use process of elimination.
We can rule out Right as the triangle is already obtuse (it can't be both).
We can rule out Equilateral as all the sides are not equal.
We can also rule out Isosceles as this triangle requires 2 sides to be equal, which clearly, they aren't.
Therefore, we are left with Scalene (C) which is your answer.
A scalene triangle has no identical sides or angles, and can be obtuse, right or acute.

26. 2x^2 +4x -10 = 0 (-4 + - (root(4^2 - 4*2*-10)))/2*2 =
(-4 + - (root(96)))/4
(-4 + (root(96)))/4 ≈ 1.45
(-4 - (root(96)))/4 ≈ -3.45
27. f(x) = 0 when any of the components that multiply together equal 0 for this function therefore x -2 = 0 x +3 = 0 x -5 = 0 so f(x) = 0 when x = 2, -3 or 5
28. It looks like it shows you how to do it
Answer:
288 will be ur ans
Step-by-step explanation:
1440 x 80/100
=1152
1440-1152
=288
321 times 23 is 7,383
3,829 divided by 1,221 is (rounded to the nearest hundredth) 3.14
(the real number was: 3.13595414)
