Answer:
A. 10
Step-by-step explanation:
The perimeter is the sum of all the outside lengths
Therefore, to find the value of x, you must do:
x + x + 5 + x + 7 = 42
3x + 12 = 42
3x = 30
x =10
Answer:
D, 35
Step-by-step explanation:
7b, if b=5, is the same as 7(5), or 7*5, which equals 35.
Answer:
Step-by-step explanation:
-5/4 is smaller than -2/3 since on the negative sides, any number who is larger is smaller.
0.75 is smaller than the square root of 3 since that equals to 1.7.
1.9 is smaller than the absolute value of -4 since that equals to 4.

Answer:
none
Step-by-step explanation:
We are given a triangle ABC with ∠A = 30°, sides a = 4 and b = 10.
According to the 'Law of Sines- Ambiguous Case', we have,
If a < b×sinA, then no triangle is possible.
If a = b×sinA, only one triangle is possible
If a > b×sinA, two triangles are possible.
So, we have,
b×sinA = 10 × sin30 = 10 × 0.5 = 5.
Now, as
4 = a < bsinA = 5.
We get, according to the rule, no triangle is possible.
