Step-by-step explanation:
<span>(14.2a + 9.8b) - (13.1b - 0.2a) - (3.7a + 4.8b)
</span>14.2a + 9.8b - 13.1b + 0.2a - 3.7a - 4.8b
(14.2a + 0.2a - 3.7a) + (9.8b - 13.1b - 4.8b)
10.7a - 8.1b
The measure of BD ≈ 5.36
<u>Step-by-step explanation</u>:
- The side BC = BD+DE+EC.
- The measure of BC = 20 and DE ≈ 9.28
- The angles ∠BD and ∠EC are both equal to 15°
- If the angles are same, then their sides are equal.
Let 'x' be the measure of BD and EC.
BC = x+9.28+x
20 = 9.28 + 2x
2x = 20-9.28
x = 10.72/2
x = 5.36 (approx.)
∴ The measure of BD ≈ 5.36
Hello,
(x+2)(x+3)(x+5)=(x+2)(x-3)(x+5)
==>(x+2)(x+5)(x+3-(x-3))=0
==>(x+2)(x+5)*6=0
==>x=-2 or x=-5
Answer:
x-int=-8, y-int=2,-4
Step-by-step explanation:
for the x-int
you set x to 0 then solve the equation to get -8
for the y-int
you set y(or in this case f(x)) to 0 then solve. You solve this by spilting this into 2 linear equations; x-2=0 and x+4=0, then you solve them both to get the two y-intercepts, 2 and -4
