Answer:

Step-by-step explanation:

A(x)=3x^2

B(x)=8x+3

A(x)=B(x)

3x^2=8x+3

3x^2-8x-3=0

factor

(3x+1)(x-3)=0

x-3=0

x=3

3(3^2)=8(3)+3

3(9)=24+3

Andrea constructed a triangle. Angle 1 and 3 are the same size and angle 2 has a measurement of 70 degrees. What is the measurem

Verdich [7]

Answer:

Step-by-step explanation:

By triangle sum theorem,

Sum of all angles of a triangle is 180°.

m∠1 + m∠2 + m∠3 = 180°

(m∠1 + m∠3) + m∠2 = 180°

2(m∠1) + 70° = 180° {Given → m∠1 = m∠3]

2(m∠1) = 110°

m∠1 = 55°

Therefore, m∠1 = m∠3 = 55°

ivann1987 [24]

Answer:96.97

Step-by-step explanation:

Given

mean height of women $\mu _w=64$

Standard deviation of height $\sigma _w=2.82$

mean height of men $\mu _=69.3$

Standard deviation of height $\sigma _m=2.71$

P $\left ( X$

P $\left ( \frac{x-\mu _w}{\sigma _w}\right )$

P $\left ( Z$

i.e. 0.9697=96.97 %
