Answer:
See explanation below.
Step-by-step explanation:
We have the statement that says that the sum of two two-digit numbers is a three digit number.
To prove that this statement is false, we only need to give a counterexample. This means that we have to find two two-digit numbers that does not sum a three digit number.
Let's take 11 and 12, if we sum them we have: 11 + 12 = 23.
23 is clearly a two digit number.
Therefore, the sum of two two-digit numbers is not a three digit number.
Just can decorate 2 full cakes. 6 divides by 3 is 2. So she decorated 2 per hour. If you do the work it’s 2 divided by 0.75 (3/4) you get 2 2/3. But that’s not a full 3 cakes so only 2. Glad to help!
Step-by-step explanation:
2x(squared)+9x+9=—1
2x(squared)+9x+9+1=0
2x(squared)+9x+10=0
multiply the coefficient of x and 10=2x10=20
2x(squared)+9x+10=0
look for two numbers that when added gives 9and when multiplied gives 20
2x(squared)+5x+4x+10=0
(2x(squared)+5x)+(4x+10)=0
find the number and letters that are common in the equations
x(2x+5)+2(2x+5)=0
(x+2) (2x+5)=0
x+2=0
collect like terms
x=0-2
x=-2
2x+5=0
collect like terms
2x=0-5
2x=-5
divide both sides by 2
2x/2=-5/2
x=-5/2
so x=-2 and -5/2

<u>Answer:</u>
The correct answer option is 'not congruent'.
<u>Step-by-step explanation:</u>
We are given two right angled triangles and we to to determine if their congruence can be proved by any postulate.
Two right angled triangles are said to be congruent if the hypotenuse and one leg of a right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle.
While here, the hypotenuse of each of the triangles are not equal and neither their corresponding legs.
Therefore, these triangles are not congruent.
