Answer:
C. m∠4 = m∠8
D. m∠2 = m∠7
Step-by-step explanation:
Here, we use the principles of alternate angles, corresponding angles and vertically opposite angles to confirm which of the statements are true. Alternate angles are always equal, corresponding angles are equal, likewise vertically opposite angles.
From the given question, it was given that a is parallel to b. Thus, it can be observed and deduced that;
m∠4 = m∠8 (corresponding angles)
and
m∠2 = m∠3 (vertically opposite angles)
m∠3 = m∠7 (corresponding angles)
So that,
m∠2 = m∠7
Thus in the question, statements C and D are true.
Answer:
115
Step-by-step explanation:
4*2+8(2) = 24
31
7(2)+30 = 44
3*2-5(2)+20 = 6-10+20 = -4+20 = 16
24+31+44+16
115
The number becomes in the unit form is a 5 hundreds and 0 tens and the 5 ones.
According to the statement
We have given that the number and the we have to write in the unit form.
So, For this purpose, we know that the
The unit form is the way to show how many of each size unit are in a number.
From the given information:
The number is a 505/10×10
Now, we have to solve this And the number becomes is
505.
And the
5 hundreds and 0 tens the 5 ones.
The unit form becomes the 5 hundreds and the 5 ones.
So, The number becomes in the unit form is a 5 hundreds and 0 tens the 5 ones.

Answer:
.8 L or 800 ML
Step-by-step explanation:
1000 ML in a L, 1000-200 = 800.
Answer:
(n+5)² - (n+3)² =
= (n² + 10n + 25) - (n² + 6n + 9)
= n² + 10n + 25 - n² - 6n - 9
= 4n + 16
= 4(n + 4) ⋮ 4
