Answer:
The answer is 1st point.
Step-by-step explanation:
By following the steps that is shown in the picture :
56x² - 8x - 7x + 1
1.Group pairs of terms with common factor,
(56x² - 8x) + (-7x + 1)
2.Factor the GCF from each group,
8x(7x - 1) - 1(7x - 1)
3.Use distributive property,
(8x - 1)(7x - 1)
Let m and r represent the maximum speeds of Malcolm and Ravi in km/h, respectively.
... (m + r)/2 = 260 . . . . . the average of their speeds was 260 kph
... 2m = r + 80 . . . . . . . . double Malcolm's speed is 80 kph more than Ravi's
The second equation can be solved for r and that expression substituted into the first equation.
... 2m - 80 = r . . . . . . . . . . . an expression for r from the second equation
... (m + 2m - 80)/2 = 260 . . . the result of substituting that into the first
... 3m - 80 = 520 . . . . . . . . multiply by 2
... m = 200 . . . . . . . . . . . . . add 80 and divide by 3
... 2·200 - 80 = r = 320 . . .substitute the value of m into the expression for r
Malcolm's maximum speed was 200 km/h.
Ravi's maximum speed was 320 km/h.
Answer:
No
Step-by-step explanation:
Summer starts in June and ends in August, so this is not valid.

Plug in the values and see which ones do not fi:-
. A 3(-4) + 2(1) = -10
that fits so it must be B, C or D.
1st angle - x⁰
2nd angle - (x+25)⁰
The angles are supplementary,
so
x+x+25=180
2x=155
x=77.5⁰ -1st angle
77.5+25=102.5⁰ - 2nd angle
