Can someone explain just one of the three

Mathematics
1 answer:
NISA [10]4 years ago

I’m going to use the second one to explain

-8j + 14 = -2(4j-7)

So you distribute -2 into the parentheses on the right side, and you get -8j + 14, which is the same as the left side. Therefore, it is a true statement. It turns from a - to a + because it is two negative numbers multiplying by each other.

1. S= squash
Z= zucchini

5s + 2z = 1.32
3s + 1z = 0.75. -2 ( 3s + 1z = 0.75)


5s + 2z = 1.32
-6s - 2z = -1.50
-s = -0.12

Squash = 0.12

5s + 2z = 1.32
5(.12) + 2z = 1.32
.60 + 2z = 1.32
2z = 1.32-.60
2z/2 =.72/2
Z= 0.36

What is x? <br><br><br> and <br><br><br> what is z? <br> A. 84<br> B. 92<br> C. 96<br> D. 109
Svetradugi [14.3K]

Step-by-step explanation:

180 = 55 + 41 + y (Angles in a triangle)

y = 180-(55+41)

y = 84

y+ z = 180 (Angles on a line)

z = 180 - y

z = 180 - 84

z = 96

The lines are parallel.

The angle opposite x is 109 because the are corresponding.

x is 109 (vertically opposite angles)
