Answer: AB 90 IB 150 IC 135 AC 90

Step-by-step explanation:

All triangles have to equal 180, if B is 60 and I is 90, 60+90=150, 180-150=30 then A=30 if a equals 30 than 60+30=90 A+B=AB (same with the others.)

Vika [28.1K]

Answer:

18 square units

Step-by-step explanation:

The given rectangle has an x-dimension of 3-1 = 2, and a y-dimension of 5-2 = 3. Stretching the x-dimension by a factor of 3 will multiply it to ...

2×3 = 6

and give you a rectangle 6 units wide by 3 units high. Its area will be ...

(6 units)(3 units) = 18 units²

Answer:

x= 23 y=88

Step-by-step explanation:

3x+23= 4x

x=23

x and y are supplementary angles so they add up to 180 so then if x is 23

23 x 4= 92

so 180-92 is 88

therefore y is 88 and x is 23

The polynomial of degree 3, P(x), has a root of multiplicity 2 at x = 3 and a root of multiplicity 1 at x = -2. The y-intercept

Maru [420]

Answer:

$p(x) = - 0.7(x - 3)^{2} (x + 2)$

Step-by-step explanation:

We have that the polynomial, has a root of multiplicity 2 at x = 3 and a root of multiplicity 1 at x = -2.

This means the factored form of the polynomial will be.

$p(x) = a(x - 3)^{2} (x + 2)$

Also, it was given that, the y-intercept is y=-12.6.

This implies that:

$- 12.6= a(0 - 3)^{2} (0 + 2)$

$- 12.6= a(- 3)^{2} (2)$

$- 12.6= 18a$

Divide both sides by 18;

$a = \frac{ - 12.6}{18}$

$a= - 0.7$

Therefore the polynomial is

$p(x) = - 0.7(x - 3)^{2} (x + 2)$
