Answer:
x = 1, x = -19
Step-by-step explanation:
1) factorise
(x−1)(x+19)=0
2) equal to 0
x−1=0 or x+19=0
x=1 or x=−19
Answer:
132 cm squared
Step-by-step explanation:
To find the area, find the area of each shape inside it and add together.
Small rectangle - Area of 4*7 = 28
Two triangles - Area of 6*8 = 48
Large rectangle - Area of 8*7 = 56
All together the area is 28 + 48 + 56 = 132
Answer:
4th number line (the one of the bottom right)
Step-by-step explanation:
First, solve the inequality, then choose the number line that mathes the solution.
3x ≤ -6
<em>Only step: Divide by 3.</em>
x ≤ -6/3
x ≤ -2
But which number line matches the solution?
We know this is going left, so #1 & #3 are out. This also has a closed circle (because of ≤ (less than/equal to)), so #2 is also out.
Number line #4 matches the solution (x ≤ -2), so it is the answer.
How many 5-digit numbers can be formed using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, if repetitions of digits are allowed?
