What is the value of the expression x−2y+√4z when x = 12 y = -3 and z = 4
Given expression,
=> x - 2y + √4z
when x = 12 , y = -3 and z = 4 ,=> 12 - 2(-3) + √4*4

ΔABC is an isosceles triangle with AB = AC, D is the midpoint of BC and
AD is joined. Prove that ΔABD ≅ ΔACD.
I kinda have a problem with triangles and congruency....little help please ?
Step-by-step explanation:
Okay, so the triangle would look something like this:
see the image attached
Since AB=AC, which is given; <ABD = <ACD, because they are the angles opposite from the congruent sides of the isosceles triangle; and <ADB=<ADC, as AD is the bisector*; ΔABD ≅ ΔACD using SAA/AAS (side-angle-angle) congruencey.
*If the bisector of an angle in a triangle meets the opposite side at its midpoint, then the triangle is isosceles, and vice versa

how to stop antixty attack?
i dont know how to spell.
Answer:
to Stop anxiety attract
take a deep breath hold it for some time and then relax your body when exhaling
Don't think Brainly is the place to ask but If your not getting enough sleep, that can be why so make sure to SLEEP and take naps at around 1:00pm and Try to wake up at 3:00pm
Aerobic activity can be calming. Avoid caffeine, alcohol and smoking which act as triggers for the attack. Regular physical activity helps in releasing the anxiety.
Easier ways are to breathe slow and deep breathing is the cornerstone of calm. Start by breathing in and out slowly.
Drink more water. Dehydration may affect anxiety in a variety of ways. And raw fruits and vegetables are the best foods for panic attack because they act as antioxidants in your body.

Evaluate when x = -3 and y= -1:
Evaluate when x = 3, y = -3 and z = -2:
Which numerical expression is obtained by substituting x= 2, y= 6,
and z = 3 into the expression shown? x - (y+z)
Evaluate when x = 3, y = 2, and z = 4:
here is the answer: so if x = 3, y =2 and z = 4 then the answer is 3 - (2+4)
Which expression is equivalent to 4( x + 3)?
Answer:
B.
Step-by-step explanation:
use distributive property
