Answer:

(0,4) and (-2,0)

Step-by-step explanation:

y=3x²+4x+4

y = -2x +4

3x²+4x+4 = - 2x +4

3x²+6x=0

3x(x+2)=0

x=0, x= -2

x=0, y=-2x+4= -2*0 + 4 =4, (0,4)

x= - 2, y = 2x + 4= 2*(-2) +4=0, (-2,0)

H + 52 72<br> ———- = —-<br> 70. 56

oee [108]

Answer:

h = 38

Step-by-step explanation:

$\frac{h + 52}{70} = \frac{9}{7}$

$h + 52 = \frac{9}{7} \times 70$

$h + 52 = \frac{9 \times 70}{7}$

$h + 52 = \frac{630}{7}$

$h + 52 = 90$

$h = 90 - 52$

$h = 38$

the answer is 38.
