Answer:
d : 4, 1, -2.
Step-by-step explanation:
There's no need for a calculator in my opinion because we can use the rational root theorem which states that the equations of this form:

Have rational roots, than the roots are of the form: 
Rewriting the equation we have:


Answer: 5 meters
Step-by-step explanation:
Cubes have six sides. 6x^2=150
150/6=25
Root 25=5
Also that should be square meters because surface area is in square measurements and volume is in cubic measurements
Answer: C) ASA = ASA
Refer to the diagram below. I've used color coding to match up the given statements with the drawing. Note how the red segments are between the blue and green angles. So we use ASA to prove the triangles are congruent.
Answer:
-1110/39 is the number
Step-by-step explanation:
We want to find the number should be added to both numerator and denominator of the ratio 29 : 36 to make it equal to 3:42
Let the number to be added be x.
Thus;
(29 + x) : (36 + x) = 3:42
The proportion symbol is essentialy a division symbol.
Thus;
(29 + x)/(36 + x) = 3/42
Cross multiply to give;
42(29 + x) = 3(36 + x)
1218 + 42x = 108 + 3x
1218 - 108 = 3x - 42x
1110 = - 39x
x = -1110/39
Answer:
B) 81°
Step-by-step explanation:
Given:
From the figure given below,
∠1 = 3x + 18
∠7 = 2x + 39
∠1 and ∠7 are a pair of exterior alternate angles. For two parallel lines l and m, cut by a transversal n, the pair of exterior alternate angles are congruent to each other.
Therefore, the angles 1 and 7 are congruent to each other. This gives,
∠1 ≅ ∠7

Therefore, the value of 'x' is 21.
Now, the measure of angle 7 can be calculated by plugging in the value of 'x' in the expression for angle 7. This gives,

Therefore, the correct option is option (B).
