Answer:
18.7 cm²
Step-by-step explanation:
To work out the area of a triangle you have to use the formula

Where "B" is the base and "H" is the height
Since these are decimals, I like to convert them into fractions which makes them easier to calculate with
The base is 4.25 cm which will turn into 
The height is 8.8 cm which will turn into 
Now we use the formula


→ Convert to improper fractions

→ Simplify

→ Convert into decimal
18.7
Answer:
1: 119 2: 61 3: 61 4: 119 5: 119 6: 61 7: 61
Step-by-step explanation:
Since we know that m & n are parallel we can prove which angles are congruent to angle 8 and which are supplementary
5: 119 (vertical to angle 8)
1: 119 (corresponding angles theorem
2: 61 (linear pair)
3: 61 (vertical to 2)
4: 119 (vertical to 1)
6: 61 (same sided interior angles theorem)
7: 61 (corresponding)
Answer:
10
Step-by-step explanation:
-20 +40 -60 +80

A table will have a length and width, so the area will be just that, the product of those two factors, so in short, simply factor the area of x²+7x-30.
now, if we do a "prime factoring" of 30, we get 2*3*5, and we can mix them as 2*5 and 3, to get the factors of (x² + 10)(x²-3).
