Follow the order of operations.
First do what is inside the parenthesis
20 + 3(7+4) + 5 + 2(7+9)
20 + 3(11) + 5 + 2(16)
Next, do the multiplication
20 + 3(11) + 5 + 2(16)
20 + 33 + 5 + 32
Then add
20 + 33 + 5 + 32 = 90
Answer:
This theorem states that 'if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent. ' This is kind of like the SAS, or side-angle-side postulate. But SAS requires you to know two sides and the included angle.
Step-by-step explanation:
Answer:
1.861(10²)
Step-by-step explanation:
Proper scientific notation only has the ones place and decimals. To get the same value again, we would need the exponent to be 2 and not -2.
The answer is b because there is a negative in the exponent and the number needs to be a single digit and 54 is double digit. hope this helps!
To solve this proportion:

Simplify 3/6, it reduces to 1/2

Then do the Criss cross method
1d = 7 ×2
d=14
Hope it helps!
