8/17-15/68
This will equal 32/68-15/68 if you equalize the denominator. The final answer is 17/68 which equals 1/4 if you reduce.
Answer:
m∠A = 20° and m∠D = 20°
Step-by-step explanation:
Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas
Let us solve the question
∵ The two triangles ABC and DEF are congruent
∴ m∠A = m∠D
∵ m∠A = x + 10
∵ m∠D = 2x
→ Equate their measures
∴ 2x = x + 10
→ Subtract x from both sides
∵ 2x - x = x - x + 10
∴ x = 10
→ Substitute x by 10 in the measures of angles A and D to find them
∵ m∠A = 10 + 10
∴ m∠A = 20°
∵ m∠D = 2(10)
∴ m∠D = 20°

<span>The expressions that cannot be factored using integral coefficients and integral constants is the below:
</span>b. 2x2 + x + 4
d. x2 - 2x - 4
For a. 25x2 - 40x + 16 the factors are (5x – 4) (5x – 4)
For c. 6x2 - 2x - 20 the factors are (2x - 4) (3x + 5)
All of them because they all have 3 sides
