13- zy+4y so all you have to do is plug the numbers in like this:
(5)(2)+4(2) then simplify so (2)(5) is 10 then (4)(5) is 20 so all there left to do is add so your final answer for question 13 is 30.

15- p^2/4-m so again plug the numbers in like this 4^2/4-3 then simplify so 4 to the second power is 16 so now it look like this 16/4-3 and then again simplify so 16 divide that by 4 to get 4 so now your problem is way small XD so 4-3 is 1 so your final answer for question 15  is 1.

~Good Luck~

95 - 3/4 what is the value of the expression
natulia [17]

Answer:377 /4  = 94 and 1 / 4  =94.25

Step-by-step explanation:

Subtract

95 − 3 /4

 = 377 / 4

Convert integer to fraction

95 = 95 / 1

Find common denominator

95 over 1

 

− 3 over 4

= ( 95 × 4 ) over ( 1 × 4 )

 − ( 3 × 1 ) over ( 4 × 1 )

= 380 over 4

 − 3 over 4

4 is the least common multiple of denominators 1 and 4. Use it to convert to equivalent fractions with this common denominator.

Subtract

380 over 4

− 3 / 4

 

= ( 380 − 3 ) / 4

= 377 /4

Simplify

377 / 4

= 94 and 1 /494

Reduce fraction to lowest terms

1 is the greatest common divisor of 377 and 4. The result can't be further reduced.

Step 2 of 2: Simplify, sub-step b: Convert improper fraction to mixed number.

Convert improper fraction to mixed number

377 /4

= 94 1 /4

377 ÷ 4 = 94 remainder 1

Given: Triangle ACD is isosceles; <1 is congruent to <3 Prove: Segment AB || Segment CD
julsineya [31]

Answer:

Segment AB || Segment CD

Step-by-step explanation:

Two lines are said to be parallel (||) if they do not meet, even when extended to infinity.

Given: <1 ≅ <3, ΔACD is an isosceles triangle.

Proof: Segment AB || Segment CD

From the diagram given,

AC ≅ AD (side property of isosceles triangle)

<3 = <4 (base angle property of an isosceles triangle)

<1 = <4 (alternate angle property)

Therefore, segment AB is parallel to segment CD.
